I think time is a major concern for every next maths student.for this there are many reasons.
First of all I will say practice matters.by coming across different problems and their logics one can increase their speed.
And secondly one should be fast with their calculations and applying shortcuts .

nice websites.......................

As per the question
Capacity of cistern + Amount of water added by inlet in 12 hours - Amount of water removed by leak =0
Assuming capacity of cistern = x

x + 60*12 - (x/8)*12 = 0
Solving we 0.5x = 720
x = 1440

30 cubes can be made. .............................

43 cubes can be made and can be calculated as (vol. of wooden block/vol of 1 cube)

@ Hello saraswathi according to answer key the ans is 30 but how i need complete solution

It seems its not related to volume....
Divide each side by 2 nd multiply the quotients
[10/2] * [7/2] * [5/2] => 5*3*2 = 30

@saraswathy can you explain the logic ?

never knew if smthg like that is also there...in first year..CS we had mail writing in syllabus.may be all that

16.15% is answer

273/1.05=260 , So the pass marks is 260
If he gets 312 then 312-260/260 *100=20%

there will be 25 question with 3 different sections 1 hr time. it will easy

(3*1) + 1^2 = 3 +1 = 4
(4*2) + 2^2 = 8+4 = 12
(12*3)+ 3^2 = 36+9 =45

The last number also follwed the same logic...so the missing number is 45

try to cmplt all questions in placement paper thts enough

@Sasikumar... I dont understand the question... I think the the problem is about remainder or something else... Bcozzz the value of 4^61 ll be very big... We cant calculate that...
4^61 + 4^62 + 4^63 + 4^64
Take 4^61 common outside
4^61(1 + 4^1 + 4^2 + 4^3)
4^61 (1 + 4 + 16 + 64)
4^61 * 85

85* 4^61

4^61(1+4+4^2+4^3)

4^61*(1+4+16+64)=85*4^61

Is it divisible by which of the following
a) 3
b) 13
c) 11
d) 17

4^61 * 85
4^61 * 5 * 17
So it is perfectly divisible by 17

Ans : 17 (Option d)

Thanks you ma..... I understood now :)

i think the ans is 17

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%

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

pick up a topic and start solving ..take up questions from discussion board later...it depends entirely on ur level...good luck

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

Is it 55 ?? Ans plzz

The 1st train crossed by Mr Haani is the one scheduled to arrive at Mumbai at 11:30 PM
the same day.ie the one that left Banglore 3 days before.
The last train crossed by Mr. Haani is the one that left Banglore at 10 pm , 3 days after.
Since SlowRun Express runs between Bangalore and Mumbai everyday,
total number of trains crossed = 7

Actually 102 should be d hight of ram, may be dats a mistake

oki..so we understud d question..now ans plz ??/ :-)

120*(100-15)/100=102

thanks but booklet says ans is 20000.. :-(

let total amount be x
x*(70/100)*(85/100)*(80/100)=9520
x=20000

ans is =27200/-
bcoz total spend shown in %=65%
remaining =35%
thats d savin 35%
x*(35/100)=9520; x=27200

Ans is 0.33 cm, we get it equating the volume.

sp=18700
l=15%
85------18700
115------?
115*18700/85=25300
he has to sell that plot to 25300 to gain profit of 15%

21505/-
is it ryt?

25,300 is the Answer

@YAGNIK, Please read this note at today puzzle section.... (Get a new puzzle every day at (IST) 11:00:00 am sharp from MONDAY to FRIDAY.)

@sohini: tnx to help... :)

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

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..

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

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

@sandeep: The question is fraction of women who earn 25000 or less not more
So the ans is b)3/4

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...

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

Ans is 20% raise,
Let Original Salary=X ; Raise be Y
10 years =120 Months, 2yrs=24 months
120*y=24*x
Solving Y=20% of X

√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

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

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

I got it Thankyou @Rakesh for your best solution.......

1000+(4000*98/100)=4920

R8 . Agree with abhimanyu kumar

4920 is the Answer

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"
