### Discussion :: Problems on Ages

1. A person's present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present?

2.  A. 32 years B. 36 years C. 40 years D. 48 years

Explanation :

Let the mother's present age be x years.

Then,the person's present age =$$( \frac { 2 } {5 } X)$$years

$$( \frac { 2 } {5 } X+8)$$=$$\frac { 1 } { 2 }$$(x+8)

2(2x + 40) = 5(x + 8)

x = 40
