Answer 2

Answer:

your answer is 32 and 40

Step-by-step explanation:

Let their present age will be 4a and 5a

After 8 years, age will be 4a+8 and 5a+8

Ratio would be (4a+8):(5a+8)

But in the above question the ratio is 5:6, therefore

(4a+8) : (5a+8) = 5 : 6

=>24a+ 48= 25a+40

=>a=8

so their present would be,

4a=4*8=32

and 5a= 5*8=40
