Question

Amit's present age is 1.5 times of Hari's present age. If after 4 years, Amit's age will be twice of Hari's age 4 year ago. What is the sum of the present ages of Amit and Hari?

Answer 1

Let hari's present age be $x$ years.

Amit 's present age $=1.5x$

After 4 years

$1.5x+4=2(x-4)$

$1.5x+4=2x-8$

$.5x=12$

$x=\frac{12}{.5}$

Hari's age ,$x=24$yrs

Amit's age$=1.5\times 24$

$=36$

Sum of present ages of Amit and Hari $=36+24$

$=60$
