Answer:
Step-by-step explanation:
Let their present ages :
Age of A =7x
Age of B =5x
After 10 years :
Age of A = 7x + 10
Aage of B = 5x + 10
They are in ratio 9:7
So,
7x+10/5x+10 = 9/7
49x + 70= 45x + 90
49x - 45x = 90-70
4x = 20
x=5
So present age of A and B :
Aage of A =7×5=35
Aage of B = 5×5 = 25
