Question

solve it plss
find the present ages

Answer 1

Answer:

Step-by-step explanation:

let the present age of A be 7x  and that of B be 5x

ages of them after 10 years

A=7x+10                        B=5x+10

but the ratio of their age after 10 years=9:7

∴7x+10/5x+10=9/7

by cross multiplication

7(7x+10)=9(5x+10)

49x+70=45x+90

49x-45x=90-70

4x=20

x=5

present age of A=7x=7*5=35

present age of B=5x=5*5=25
