Question

Kamla is 4 times as old as her son. 5 years ago her son was 1/7 of her age. What is Kamla's age now?

Answer 1

Answer:

40 years

Step-by-step explanation:

1) Suppose Kamla's son present age is X year.

So Kamla's present age is 4X year.

2) 5 years ago :

Son's age was= X-5 year

Kamla's age was= 4X-5 year

5 years ago, Son was 1/7 of Kalma's age.

Son's age = Kamla's age / 7

X-5 = (4X-5)/7

7(X-5) = 4X-5

7X-35 = 4X-5

7X-4X = -5 + 35

3X = 30

X = 10 year.

So Kamla's present age is 4X = 4(10) = 40 years.
