Answer 1

the ratio of ages of A and B is

3:5

______________

let age of A = 3x

let age of B =5x

__________________

after 5 years,

age of A= 3x+5

age of B= 5x+5

______________

the ratio of their age of after five years is 2:3

__________________

so

3x+5/5x+5 = 2/3

3(3x+5)=2(5x+5)

9x-10x=10-15

x= 5

__________

present age of B is 5x

= 5(5)

= 25 years

your answer is 25 years
