Question

The age of aA is 5 years more than that of B. Five years
ago the ratio of their ages was 3:2. Find their present ages.​

Answer 1

let age of a be x and age of b be y

acc. to que.

Case 1

x=y+5 .....(1)

Case 2

x-5/y-5 = 3/2

put x=y+5

y+5-5/y-5=3/2

y/y-5 = 3/2

2y =3y-15

y=15years

put y = 15 in eqn (1)

x=15+5

x=20years
