Question

The ages of a and b are in the ratio 5 ratio 7 4 years from now the ratio of their ages will be three days of for the present age of b is

Answer 1

Let x be the common age between A and B

Their ages are 5x and 3x respectively.

After 6 years,

Age of A=5x+6

Age of A after 6 years=7x

According to the question,

5x+6=7x

5x-7x=-6

-2x=-6

x=-6/-2

=3

Thus,

Present age of A

=5x

=5*3

=15
