## 4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it?

A) 35

B) 40

C) 45

D) 50

Let 1 man’s 1 day work = x and 1 woman’s 1 day work = y.
Then, 4x + 6y = 1/8 and 3x + 7y = 1/10
Solving these two equations, we get:
x = 11/400 and y = 1/400
10 woman’s 1 day work = (1/400 x 10) = 1/40.

Hence, 10 women will complete the work in 40 days.

## A is two years older than B who is twice as old as C. If the total of the ages of A, B and C be 27, the how old is B?

A) 7

B) 8

C) 9

D) 10

Let C’s age be x years. Then, B’s age = 2x years. A’s age = (2x + 2) years. (2x + 2) + 2x + x = 27 5x = 25 x = 5.

Hence, B’s age = 2x = 10 years.

## When 1/4 of a number subtracted from 1/3 of the same number, the remained obtained is 12. The number is:

A) 144

B) 72

C) 120

D) 63

1/3 of the number = 1/3(x) =x/3

1/4 of a number subtracted from 1/3 of the number gives 12.

x/3-x/4 =12

x/3×4/4 – x/4×3/3 =12

4x/12 – 3x/12 =12

(4x-3x)/12=12

4x-3x=12×12

x=144

Therefore,the number is 144.
