12.5% profit

If CP=100 & Weight=100,then at SP=100 =No profit No loss
When,Price=100 & Weight=80, then Profit% =100*(100/80)-100= 25
When,Price=90 & Weight=80, then Profit%=90*(125/100)-100= 12.5

Suppose CP=100 rs, wt=100 then value of his merchandise=100*100=10000
After selling the value he retains= 80*90+20*100=7200+2000=9200
So the value decreases after selling the product Hence loss of 8%

A man pays off 3/20th of his debt every month. At the end of 6 months his balance debt is 290rs. How much debt (rs) has he cleared off every month?

a) 500 b )450 c) 435 d) 400

Reply Like? Yes | No

(10 years ago)

Let x be the total amount he has to pay
3/20 of x is => 3x/20
For 6 months he might have paid 6*(3x/20) = 9x/10
Balance debt => x - 9x/10 = 290
x = 2900
Every month he cleared 2900*3/20 = 435

13 chairs and 5 tables were bought for 8280rs. If the avg cost of the table will be 1227rs what is the avg cost of a chair?

Reply Like? Yes | No

(10 years ago)

Let C be the total cost of 13 chairs nd T be the total cost of 5 tables
Then
C + T = 8280
Given Avg. cost of table is 1227
Then T/5 = 1227
T = 1227*5 = 6135
Total cost of 5 tables T = 6135
Now C = 8280 - T
C = 8280 - 6135 = 2145
Total cost of 13 chairs = 2145
Avg. cost of 13 chairs ll be => 2145/13 = 165

Ans : 165

40% of the employees of a certain company are men and 75% of the men earn more than 25000rs per year. If 45% of the companys employees earn more than 25000rs per year. What fraction of the women employed by the company earn 25000rs per year or less?

a) 1/4 b) 3/4 c) 1/3 d) 2/11 I NEED COMPLETE SOLUTION PLS HELP ME

Reply Like? Yes | No

(10 years ago)

Answer: a) 1/4
Reasons:
Assume Total number of Employees in Company = 100
Number of Men = 40, Number of women =60
Number of Men who earn more than 25000 = 75* 40/100 = 30
Number of Total Employee who earn more than 25000 = 45*100/100 = 45
Number of Women who earn more than 25000 = 45-30 = 15
Fraction = 15/60 = 1/4

Like? Yes | No (1)

(10 years ago)

I think the answer is 3/4.
Because 15 out of 60 women earn more than 25000, so, 45 women earn 25000 or less than that.
So, answer is 45/60=3/4..

Like? Yes (2) | No

(10 years ago)

Agree Harika..sorry I didn't realized that we need to find 25000 or less.
Answer should be 3/4

Like? Yes | No

(10 years ago)

let total no of employee=100
male=40
female=60
no of employee having earning more than 25000=45
no of men employee having earning more than 25000=75%of 40=30
so no of women employee having earning less than or equalto 25000 is=60-(45-30)=45
so fraction is 45/60==3/4

Like? Yes | No

a) 10% b)9 % c) 8% d) none I NEED COMPLETE SOLUTION PLS HELP ME

Reply Like? Yes (1) | No

(10 years ago)

Ins is B.
explanation:
8% interest on 2000=160
15/2% interest on 4000=300
17/2% on 1400
So what is R for remaining rupees? ? Is to b found. ..
Total annual interest is 8.13% so total interest will be 813.
Now 160 +300+119=579
So 813 - 579 = 234
Now r can be found because I=234, p=2600, n=2600 by simple interest formula which is >> I = PRN/100
So u wiil get R = 9.
Hope my explanation would help you...

A woman is walking down a downward-moving escalator and steps down 10steps to reach the bottom. Just as she reaches the bottom of the escalator, a sale commences on the floor above. She runs back up the downward moving escalator at a speed five times that which she walked down. She covers 25 steps in reaching the top. How many steps are visible on the escalator when it is switched off?

Reply Like? Yes | No

(10 years ago)

Let s be the number of steps on the escalator.
Let a be the speed of escalator and b speed of woman.

The time while the woman moves down 10 steps equals the time that the
escalator moves s-10 steps.
(s-10)/a = 10/b ----(1)

Also the time that woman moves 25 steps equals the time that the escalator moves (25-s) steps.
(25-s)/a = 25/5b ----(2)

(1)/(2) gives
(s-10)/(25-s) = 2
Solving s = 20 steps

Dear Rakesh ,
I am again in confussion please slove it as early as possible

x^1/2 + y = 7
x + y^1/2 = 11

prove that x = 9 and y = 4

Reply Like? Yes (5) | No

(10 years ago)

√x + y = 7
x + √y = 11

√x + y = 7
=> x = (7-y)^2 = 49 + y^2 - 14y

x + √y = 11
=> y = (11-x)^2
=> y = (11 - 49 - y^2 + 14y)^2
=> y = (y^2 -14y +38)^2
=> y = y^4 + 196y^2 + 1444 -28y^3 -1064y + 76y^2
=> y^4 - 28y^3 + 272y^2 - 1065y + 1444 = 0
at y=4, above eqn satisfies
=> (y-4)*(y^3 -------) = 0
=> y = 4
so, x = 9

Like? Yes | No (2)

(10 years ago)

NO Rakesh we have to prove that x= 9 and y=4 ....
we can't satisfy any equation to put the value of x and y...
.imagine we don't know the original value of x and y ,now prove that

Like? Yes | No

(10 years ago)

for ex
we have to solve x^5 + x - 2 = 0
here we see that at x = 1 , above eqn satisfies
so, from remainder theorem, (x-1) is a factor of the eqn
now divide x^5 + x - 2 by (x-1)
=> (x-1)*(x^4 ---some terms) = 0
=> x = 1
the same thing i have done in the ans.

otherwise
x^1/2 + y = 7
x + y^1/2 = 11

let x = a^2 & y = b^2

a + b^2 = 7 & a^2 + b = 11
subtract
(a^2-b^2)+(b-a) = 4
=> (a-b)(a+b-1) = 4 = 1*4 = 2*2 = 4*1 (for integral values)

if a-b = 1 , a+b-1 = 4 => a = 3, b = 2
if a-b = 2 , a+b-1 = 2 => a = 5/2 , b = 1/2 doesn't satisfy eqn
if a-b = 4 , a+b-1 = 1 => a = 3 , b = 2

so, a = 3 , b = 2
=> x = 9 , y = 4

What percentile should i get in e litmus for interview call???

Reply Like? Yes | No

(10 years ago)

WHAT ARE BASIC RULES???

• Divide the time as: 45-50 minutes for Quant, 45-50 minutes for Reasoning and Last 25-30 Minutes for English(not even a single second Exrta for English)
• Start solving paper from either Quant or Reasoning as according to your preference and command over the subject/topics.
o Most of you, will be tempted to start the paper from English coz its the easiest one, but trust me... That ain't gonna help you.
• Then go to the next section remaining among Quant and Reasoning
• And at last in Last 25-30 minutes go for English.
HOW TO SOLVE EACH SECTION???
• REASONING:
o Don't even look at the first questions... just turn the page and come to the last question i.e Data Interpretation. It will be a lengthy question BUT it will have FOUR questions associated with it. So TAKE YOUR TIME(even 15-20 minutes) and solve it. Don't get panicked that "I am taking too much time to solve this??? What about other questions??? Should i try other ones???" NO!!! FOCUS AND SOLVE THE QUESTIONS... AND ALL FOUR OF THEM.
o Now Dont look at 4th question until unless you are quite( i mean QUITE) good at Crypt-Arithmetic, you will juss waste your Precious time in analyzing it... for those who have no idea about What is Crypt-arithmetic??? "SEND+MORE=MONEY" type questions, where you have to find the value of the Alphabets used in the given equations.
o After you have completed Data interpretation, Skip 4th one(Crypt-arithmetic) and come to 3rd question i.e. Data Sufficiency(ek se answer aa jayega...dono se aajegaa...dono se ni ayegaa type). There are four questions... among them if you try... will be easily able to solve 2-3 questions(20-25 minutes).
o Now you have Solved 4+2(atleast questions), what it means.... It means you have secured 50+ marks in Reasoning section i.e. 80+ Percentile in Reasoning. Quite easy na???? :)
o Don't waste time in looking at other questions in reasoning section..... mere buss ki to ni theee... baaki apki shradhaa!!!
• QUANTS:
o So till now you have completed 5+ question in Reasoning in 40-50 minutes... now its turn for Quant.
 Start from beginning:
 Read the question and decide weather you are able to solve it Right Now(coz its from the part in which you have stronghold, or from the topic which you have studied Previous Night :P) OR it will take some time you to solve it OR it is from the topic you have skipped/ no idea about the question.
 If it is First case-->> SOLVE IT AT THE MOMENT(Dont worry about time even if you take 8-10 minutes to solve a single question as long as you are sure that you are solving it Correctly)... and Tick mark the question.
 If it is Second case -->> Mark the circle on the question no. and move on to next question.... so that you can look at it in next round.
 And if it is Third case-->> Cross mark the question.. so that you do not waste(each second counts) your time in going through that again.
 By solving this way.... If you are able to solve 2-5 questions..... That is sufficient ... Trust me it is even more than juss sufficient...
 If You have solved 2+ questions(atleast) your score will be 20+ i.e. 60+ Percentile in Quants. Quite easy na??? :)
 CAUTION: Dont get Tempted to solve More then 8-10 questions(if you are too good in quants) else 5-7 questions are Enough.
• ENGLISH:
o Hmm... Done with quants and reasoning and time now remaining is around 25-30 minutes..... So get going... :)
o English is easiest part in elitmus.
o Start from first question...... and when you reach Paragraph based questions, SELECT TWO FROM THE GIVEN THREE WHICH ARE SMALLER IN CONTENT.
o That's the only key in English part... choose wisely coz you wont have that much time to solve the third one, in case you manage to get some extra time go for the third Para too.
o So around 12-16 questions in will be enough.
o With 12+ questions you will have 100+ score i.e. 90+ or 93+ percentile in English section .
So All in all you have got now:
• 5+ question in quant
• 5+ in reasoning
• 10+ in English
Means you got 80+ and 60+ and 90+ percentile SO YOUR OVERALL ELITMUS PERCENTILE IS 90+ AS PROMISED ;)

CAUTION: I repeat Don't get Tempted to solve More questions, coz negative marking will impact your percentile very badly.

Books and Tricks suggested for preparation(On Public Demand :P )
Quant: Abhijeet Guha for basics, and then go for Quantitative CAT (Arun Sharma).
Reasoning: Logical Reasoning CAT(Arun Sharma)
Verbal: Do practice of Paragraphs and Sequence based question. For grammar "Which Feels Right Is Right :P "... And for word meaning/antonym/synonym.... Juss one day before exam "take a quick Scan of 200+ words".... If you are Lucky you might get one of them over there in test... and as you have scanned once, jss last night... you will be able to "Guess the right choice :D "

That's all about how to score 90+ percentile in ELITMUS. Hope this will be helpful in your preparation. Best wishes. :)(:

Welcome friends :)

These four posts(Second one The Trick being the KEY post) are for all those who are preparing for ELITMUS and also will help you in resolving some of your queries regarding Preparation, Result, Percentile, Chances of getting Interview Calls, Right time we should go for Elitmus...etc. Before i start giving tips on "How to get 90+ percentile in ELITMUS" ... i think it will be good to give a brief introduction about ELITMUS.

WHAT IS ELITMUS???

Elitmus is a reputed "Bicholiya" i.e. Middle Layer between JOB SEEKERS(we :p) and JOB PROVIDERS(Companies mostly IT Sector related). It is an organization which organizes APTITUDE TEST, basic hiring process(first hurdle in getting job).

Companies get benifitted coz their overhead of selecting suitable candidate is being taken care by elitmus.

We, students get benefited coz we get a platform where we can showcase our caliber and thus gets noticed by job providers(companies)

Elitmus is getting benefited coz......coz of course they are charging both the parties for the SERVICE they are providing.

Soooo.........Everyone is getting benefited... a win win situation :)

HOW IT WORKS???

Its quite simple......Following are the steps:
• Give ELITMUS exam.
• Get good percentile.
• Get calls for interview from companies.
• Crack the interview and get the job.
Told you.... its quite simple!!! ;-)

SCHEDULE, PATTERN AND SYLLABUS???

Elitmus organizes the exam in various cities all over INDIA. Go to ELITMUS WEBSITE register and then select the Date and Place where you want to attend the exam. After that make payment. Once payment is done you will receive your call letter 1-2 days prior to the date of exam on the email id you have provided during registration.

Paper contains three sections:
• Quantitative aptitude(20 questions)
o Questions from Time and Distance, Work, Average, Percentage, Profit Loss, Geometry, Probability, Permutation and Combination, Number System, Algebra
• Reasoning aptitude (20 questions)
o Divided in 5 parts: Data sufficiency, Crypt-arithmetic, Data interpretation, Logical deductions based relational questions(2).
• English(20 questions)
o 3 passage, 2 fill in the blanks, 2 find the proper sequence of sentence, 2 word meaning etc.
Time given to solve the whole paper 2 hours.

Books for preparation: Quantitative CAT Arun Sharma.... Time ya kisi bhi CAT level ka matter le lo.Prepare from any CAT preparation book.

As the post is getting to Lengthy... so i am breaking the topic into two posts. Here is the link of Final post explaining "How to get 90+ percentile in ELITMUS"
Must go through--->>>The Trick...
Update no. one ON DEMAND: If you have any Queries go through Second Last post of this blog dedicated to FAQ's--->> Frequently Asked Questions(FAQ's)
Update no. two ON DEMAND:As many of you keep on asking about Overall Percentile... Please Refer this Last post -->> Estimating Overall Percentile

Best wishes for exam.... Be calm during exam.. coz no matter how great you have practiced, your result Always depends upon "Whether you are able to hold your nerve during exam or not" :)

a-x represent in the form of 1/a^x so even if u increase x value linearly then 1 divided by positive number power linear increased value should be linearly decreased........ex:-x=1,2,......,a=2 and for x=1 result 1/a^x=1/2^1=0.5 and for x=2,1/a^x=1/2^2=1/4=0.25 so there is linear decrease of a^-x value

Today's Puzzle

Let the amount invest is x & 800000-x

40% of 800000=320000

profit from 1st=3.5 lacs
loss from second=16%
total loss=overall profit - profit from 1st
=350000-320000=30000
Loss=30000
Principle amount to 2nd=30000*100/16=187500
investment to second=187500
investment to 1st=80000-187500=612500

Ratio=612500/187500
=49/15

3men, 4women, 6children can complete a work in 7days. A women does double the work a man does and a child does half the work a man does . How many women alone can complete this work in 7days?

a)7 b)8

Reply Like? Yes (3) | No

(10 years ago)

7 Women

If 1 day work of 1 Man, 1 Woman & 1 Children is (1/M) , (1/W) & (1/C) respectively
Then 1 day work of 3 Men, 4 Women & 6 Children =(3/M)+(4/W)+(6/C)= 1/7 -----(i)
Given women does double the work a man, so (2/M)=(1/W) or 1/M =1/2W ----(ii) and
child does half the work a man, so (1/2M) =1/C ,so from (ii), (1/C)=(1/4W) ---(iii)
Eqn. (i) becomes, (3/2W)+(4/W)+(6/4W)= 1/7 , On solving, W=49
1 Woman can complete the work in 49 days
So to complete the work in 7 days 49/7= 7 women are required.

the avg of five natural numbers is 150.a particular number among five exceeds another by 100.the rest 3 numbers are lie between these two numbers and they are equal.how many different values can the largest number among five can take?

Reply Like? Yes | No

(10 years ago)

19

Total of all five numbers, a,b,c,d & e= 150*5= 750
If 'e' is the largest number & 'a' is the smallest number, then e-a= 100
As all other three numbers are same say= 'b' ,then
a+b+b+b+e= 750 ---(i) or (e-100)+3b+e=750 or 2e+3b=850
So e=(850-3b)/2 ----(ii)
'b' can take even values between 130 to 170
For b=130, e=230, a=130
For b=132, e=227, a=127
.
.
.
For b=168, e=173, a=73
For b=170, e=170, a=70
So for 'b' to be middle value between 'a' & 'e' , 'e' can take value 173, 176, 179,......., 227
Finding the number of 'n' values of 'e' , 227= 173+(n-1)3 , n=19

Reply Like? Yes (1) | No

Hi Akanksha,

f'(x) = -3x^2 + 6x + 2
now for slope of f(x) to be maximum, the value of f'(x) must me maximum.
so, f'(x) is a quadratic equation with curve bent downwards. So, the local maxima will be the global also.
now, calc f''(x) = 0.
you get the point of global maxima and hence the ans.....

slope of f(x) is maximum at x = 5.

plz tell me if not understood.

f(x) = 2x + 3x^2 - x^3 - 27

to find slope of a function f(x) find f'(x)
slope = f'(x) = 2 + 6x - 3x^2 = g(x) let

now we have to find maxm of g(x)
g'(x)= 0 gives the point of maxm/minm
if g''(x) > 0 then g(x) has mimm
if g''(x) < 0 then g(x) has maxm

f''(x) = (6 - 6x) = 0 => x = 1

f'''(x) = -6 < 0 => f'(x) has a maxm at x = 1

maxm slope = f'(1)= 2 + 6 - 3 = 5

2+4+6+8+10+........=200,
Arithmetic series Sum =(n/2)[2a+(n-1)d], Herea=2,d=2,
So (n/2)[2*2+(n-1)2]=200, n^2+n-200=0, n=13.65

5 teachers spent as much as 4 engineers

In a dark room with no equipments other than a clock,you are given a pendulum.how can you measure your height now?

Reply Like? Yes (4) | No

(10 years ago)

Use formula s = ut+1/2 at^2
s= Height from which pendulum ball is freely dropped
u=Initial velocity, it would be 0 when dropped freely
t=time taken to reach ground
a=gravitation pull = 9.81 m/s2

So you need to start counting time using clock as soon as you drop the pendulum ball from your head in standing position & stop it the time when i reaches ground (when you hear the sound it hitting ground ). This will give you t.
Putting in formula Height = 1/2*g*t^2
You should get the answer

Like? Yes (4) | No

(10 years ago)

Time period of pendulum is given by 2*3.14*(sqrt(height of rope/gravity)).
gravity=g=9.81
using clock you can find the time period of pendulum.(average time for 1 oscillation).using the formula from time period you can measure the heigth of the rope. Then using the rope you can measure your own height.

a) 13 1/3%
Quantity of sugar in 40 lts.=40*(10/100)=4 lts., So quantity of water=40-4=36
On evaporation of 10 lts. water remains=36-10=26
% of sugar in final solution=100*4/(26+4)= 40/3= 13 1/3

@sravya thanks for answer
but m not able to understnd why u r taking number f terms 120 while applying A.P.bcz
3(1,2) is made up of two terms
5(1,2,2) is made up of three terms
7(1,2,2,2) is made up of four terms
thus 3,5,7 consists of 9 terms thus resulting sequence which forms an A.P. will not have 1230 terms but will have some less number of terms

@naina..ya i said one is wrong..no of terms will be reduced....so,this mthd i have solved.....
1 2 1 2 2 1 2 2 2 1 2 2 2 2 1 2 ......
=(1+2),(1+2+2),(1+2+2+2),(1+2+2+2+2)......
if N be no. of terms then
N=(1+1)+(1+2)+(1+3)+(1+4)+...
N= n+ n(n+1)/2 = (n^2+3n)/2
now (n^2+3n)/2 = 1230 => n^2+3n=2460
if n=48, (n^2+3n)=2448 & N=2448/2=1224
so series will be
sum of (1224 term + 6 term)
[(1+2)+(1+2+2)+(1+2+2+2)+(1+2+2+2+2)+...+(1+2+2...48 times 2)]+(1+2+2+2+2+2)
so no. of 1's in series=49
no. of 2's in series=(1230-49)=1181

sum of series= 49*1+1181*2 = 49+2362=2411

ans 2411
