Today,aditi is as old as barkha will be 9 yr from now.5 yrs ago,aditi was 1.5 times as old as barkha was at that time.what will be the sum of ages of aditi and barkha 4 yr hence?

Answer 1

if their ages today are a and b, then we have

a = b+9
a-5 = 1.5(b-5)

b+9-5 = 1.5b - 7.5
11.5 = .5b
b = 23
so, a=b+9=32

(a+4)+(b+4) = 36+27 = 63
