25 26 27 28

Solution!
Given that
A/B = 3/7 ...(1)

and
B-A = 16 ...(2)
Put value of A from equation(1) in equation(2)
B-(3/7)B = 16
(7B-3B)/7 = 16
4B = 112
B = 28

Hence Age of B is 28 years..

Question No 7

A is two years older than B who is twice as old as C. The total of the ages of A, B and C is 27. How old is B?

Select the correct answer

10 9 8 7

Let the age of C = x.

Then

Age of B = 2x

Age of A = 2 + 2x

The total age of A,B and C =27

(2+2x) + 2x + x = 27
5x = 25
B's age = 2x = 2 * 5 = 10.

Bill's age is 1/3 of Mike's age, who is 60% of James' age. Tom is twice as old as Mike. What is the ratio of Bill's age to Tom's age?

Select the correct answer

1/6 1/3 3/1 3/2

Solution!
Let Bill's age is Z, Mike's age is Y and Tom's age is X.

Given that
Z = (1/3)Y
and
Y = (60/100)X
Y = (6/10)X

Tom's Age is double of Mike's age mean his age is 2y.
Now Bill's age is (1/3)Y and Tom's age is 2Y and ratio between them is
[(1/3)Y] / 2Y
(1/3)*(1/2) = 1/6

Hence ratio between Bill's and Tom's age is 1/6..

Select the correct answer

4 5 6 10

Solution!
Let the speed of the stream be x km/hr.

Then,
Speed downstream = (15 + x) km/hr

Speed upstream = (15 - x) km/hr

So, [30/(15 + x)] + [30/(15 - x)] = 9/2
900/(225 - x*x) = 9/2

x = 5 km/hr.

Question No 28

A is thrice as good as a workman as B and therefore is able to finish a job in 60 days less than B.Working together,they can do it in

Select the correct answer

20 days 22.5 days 25 days 30 days

Solution!
Ratio of times taken by A and B = 1/3

The time difference is (3 - 1) 2 days while B take 3 days and A takes 1 day.

If difference of time is 2 days, B takes 3 days.

If difference of time is 60 days, B takes (3/2 * 60) = 90 days

So, A takes 30 days to do the work.

A's 1 day's work = 1/30

B's 1 day's work = 1/90

(A + B)'s 1 day's work = (1/30 + 1/90) = 4/90 = 2/45

Hence, A and B together can do the work in 45/2 = 22.5 days.

Select the correct answer

45 km/hr 50 km/hr 54 km/hr 55 km/hr

Solution!
Speed of the train relative to man = (125/10) m/s
= (25/2)m/s
= (25/2) * (18/5)km/hr
= 45 km/hr

Let the speed of the train be x km/hr.
Then,
relative speed = (x - 5) km/hr

x - 5 = 45
Hence, x = 50 km/hr.
