Answer 2

Answer:

The answer will be;

mother's age = 24

son age = 6

Step-by-step explanation:

Ratio of the present age of mother and son;

= 4:1

Thus, mother's age = 4x. (for some integer x)

and son's age = x

After 12 years;

mother's age = 4x + 12

son's age = x+ 12

and the ratio of their age = 2:1;

Thus,

mother's age/ son's age = 2/1

(4x + 12)/(x + 12) = 2/1

4x + 12 = 2x + 24

2x = 24 - 12

x = 12/2

x = 6.

Thus son's age = 6 years old.

and, mother's age = 6(4)

= 24 years.

That's all.
