Question

A present age of A and B are in the ratio 7:5 ten years later, their ages will be in the ratio 9:7. find their present age

Answer 1

Let the present ages of A And B be 7x and 5x

therefore, according to the problem-

7x+10/5x+10=9/7

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

Or, 49x+70=45x+90

Or, 49x-45x=90-70

Or, 4x=20

Or, x=20/4=5

So,the present age of A=7(5)=35

And, the present age of B=5(5)=25
