surabhi choudhary 9 years ago

divisibility of 4- last2 digit should be divisible by 4.

therefore last 2 digit can be filled by 5 ways i.e, 04,12,32,44,52.

and for 5 digit no. there 1st place can be filled by 5 ways.. and therefore totally no of 5digit = 5x6x6x5=900.

for divisible by 4 last two digits should be divisible by 4
then last two

-- -- -- 0 4
-- -- -- 1 2
-- -- -- 2 0
-- -- -- 2 4
-- -- -- 3 2
-- -- -- 4 0
-- -- -- 5 2
last two digits selected as 7 ways
first digit selected as 3 ways(because first digit should not be start with 0)
second digit selected as 3 ways
third digit selected as 3 ways
so total number of combinations will be=3*3*2*7=126 ways

Reply Like? Yes (1) | No

MURUGESAN.P 9 years ago

fresh milk=100 liter(contains 90% water)
condensed milk contains 20% water
removing waters from fresh milk=10% of 100
milk without water is 10 liter
now,
remove water from condensed milk (ie) 80% 0f 10 liter
condensed milk obtained from fresh milk is,
(80/100)*10=8 liter
answer is 8 liter

12.5 liters

100 liters of fresh milk will contain 10 liters of milk, which accounts for 80% of milk in condensed milk,
So condensed milk that can be obtained=10*100/80=12.5 liters.

MURUGESAN.P 9 years ago

initially wine=50 liters
1st process:
wine=45 and water= 5
ratio=9:1
after 1st process, we have to remove 5 liter wine which is equal to 9/10 of whole portion.
therefore whole portion=5/0.9=5.55.
removal of wine=5 means (45-5)=40
removal of water=0.55 means (5-0.55)=4.45+5=9.45
2nd process:
wine=40 water=9.45
ratio=1:4 (approximately) otherwise you can keep (40:9.45) as ratio.

here juice is constant liquid.
so in the new ratio juice has 20 parts out of 33 parts(total 20+11=33)
total amount of water in the new mixture=(55/20)*11=30.25

Anusha 10 years ago

Initially, the question seemed wrong since the sum of 3 odd numbers can never be an even number.
But to be logical, there are many ways to answer this.
1) 13 (in base 7) + 13 (in base 7) + 13 (in base 7) = 42 (in base 7) = 30 (in base 10).
This is also valid for many odd bases. 11 (in base 9) + 11 (in base 9) + 11 (in base 9) = 33 (in base 9) = 30 (in base 10).
2) 15+15 = 30 The third blank can be omitted because there is no instruction that three blanks should be filled.
3) If we allow decimals, 19.5+9.5+1 = 30 In certain number system, they use ,(comma) instead of .(decimal point). Decimal point or comma can be used because ".(dot) and ,(comma)" are there in the list of "you can use" in the given question. Also, it is given that we can repeat numbers. So, I use 1 and 9 to make 19. There are many such possible combinations.

Reply Like? Yes | No

neha gupta 9 years ago

As we know inverse of HP is AP so acc to ques:
third term of AP is 11/7 and seventh term is 31/7
thus according to relation a+(n-1)d=n th term
a+(3-1)d = 3rd term = 11/7
a+(7-1)d = 7th term = 31/7
i.e.
7a+14d=11
7a+42d=31
solving above two we get
a= 1/7 and d=5/7
so eight term = a+7d = 1/7 + 7*(5/7) = 36/7
so for HP required answer is 7/36

a) 5000 b) 6000

Reply Like? Yes (1) | No

Let the ratio of wages be x then
Original wages = 22x
New wages = 25x
Let the ratio of workers be y then
Original workers = 15y
New workers = 11y
Thus original bill = 22x * 15y
New bill = 25x * 11y = 5000
So by solving We get xy = 200/11
Then original bill = 22x * 15y = (22 * 15 * 200)/11 = 6000
So original bill = 6000

The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:

Reply Like? Yes | No

neha gupta 10 years ago

CP of 20 articles = SP of x articles
Let it be equal to 100
then CP of 1 article = 100/20 = 5
SP of 1 article = 100/x
P% = 25
P on one article = SP of 1 - CP of 1 = ((100/x) - 5)
So
((100/x) - 5)/5 = 25/100
(100/x) - 5 = 25/20 = 5/4
100/x = 5/4 + 5 = 25/4
x = 100*4/25 = 16
so number of articles sold = 16.

Consider the graph G0 with 3 components which are triangles. G0 has 9 vertices labeled
A to I and 9 edges (A, B), (B, C) … as shown below.
If each vertex of G0 is assigned a red or a green color, then we say that an edge is
colored if its ends have different colors.
Ajai and Rekha color the vertices of G0 in the following manner. Ajai proposes a color
(red or green) and Rekha chooses the vertex to apply this color. After 9 turns, all the
vertices of G0 are colored and the number of colored edges is counted.
Suppose Ajai would like to maximize the number of colored edges while Rekha would
like to minimize the number of colored edges. Assuming optimal play from both players,
how many edges will be colored? Explain ur reasoning.

Here x is missing.
But if we consider p to be x
then option C is correct as its value can be calculated by using statement 1 alone(p=0, p=-2).
and using statement 2 alone(p=0, p=-1) but p have three values so final answer is p= 0, -1, -2.

Arun starts from cochin to trichy @ 11am.He travelled @60 kmph & covered 1/2 the dist in 2 hours.@ what uniform speed should he travel to reach trichy by 4pm? a)60 b)55 C)40 d)45

neha gupta 10 years ago

As Arun has covered half distance in 2 hours by travelling at 60 km/hr
thus total distance = (2*60*2) = 240
now distance to be covered = 120 km
time left = 3 hrs(2 hrs to 11 AM is 1 PM so time left = 4 PM - 1PM = 3 hrs)
speed required = 120/3 = 40 km/hr
so answer is C.

Radius of circular field can be calculated as per given values
2*22/7*r=7700/14
r=175/2
Now we can easily calculate the area of the circular field =22/7*175*175/4
=24062.5

Reply Like? Yes (2) | No

Swathi 10 years ago

ans- 1:6
16.66% profit means there is one part water and 6 part is pure wine. so the required ratio of water and wine in the mixture is 1:6

A train running at 7/11 of its own speed reached a place in 22 hours. How much time could be saved if the train would have run at its own speed?

Reply Like? Yes (3) | No

kriti kankariya 10 years ago

let original speed be s and time be t
7/11 *s *22 = s *t (distance covered both the time will be same)
t= 14
time saved = 22-14 = 8hrs

paras jain 10 years ago

let original speed be x and time be y
so we need to compare both because the distance is same in both the cases..
(7/11) *X *22 = X *Y
Y= 14
so,, time saved = 22-14 = 8hrs

a large tanker can be filled by two pipes a and b in 60 minutes and 40 minutes respectively. how many minutes will it take to fill the tanker from empty state if b is used for half the time and a and b fill it together for the other half

Reply Like? Yes (2) | No

kriti kankariya 10 years ago

time taken by a = 60min
time taken by b = 40min
b is doing work for x min and a and b together doing it for x min
i.e.
x/40 + (1/40 + 1/60)x = 1
on solving x = 15min
so total time needed = 2x = 30min

Reply Like? Yes (1) | No

kriti kankariya 10 years ago

relative distance = 200m
relative speed = 2km/h = 2*10/36 m/s
time taken to catch = 200/(20/36) = 200*36/20 = 360sec = 6min

neha gupta 10 years ago

Let the distance travelled by thief before being caught be x km
speed of theif = y km/hr
time = x/y ...............(i)
then distance of police = (x + 0.2) km
speed of police = (y + 2) km/hr
time = (x + 0.2)/(y + 2) ..................(ii)
putting (i) and (ii) equal, we get
x/y = (x + 0.2)/(y + 2)
x/y = 0.1 hr = 0.1 * 60 = 6 minutes.
