Question

Ram"s father is twice as old as he is.Twenty year ago Ram's father was 7 times as old as his son. Find there present age.

Answer 1

Dear student,

Let ram 's age be x. his fathers age = 2x

Twenty years ago ram 's age = x - 20 and father 's age = 2x - 20

According to the question,

2x - 20 = 7( x-20 )

2x - 20 = 7x - 140

-20 + 140 = 7x - 2x

120 = 5x

$\frac{120}{5}=x$

24 = x

Thus, ram 's age = 24 and his father 's age = 2x = 2 $\times$ 24 = 48
