Expert Answer:
Let the present ages of A and B are 7x and 5x respectively.
After 10 years there ages will be :
7x+10/ 5x + 10 = 9/7
9 (5x + 10) = 7 (7x + 10) ..............(cross multiply)
45x + 90 = 49x + 70
90 - 70 = 49x -45x
20 = 4x
x = 20 / 4 = 5
Present age of A = 7x = 7 x 5 = 35 years
Present age of B = 5 x 5 = 25 years
