ages will be 9:7, find their present ages

:

The easy way to do this is by using a "multiplier"

let x = the multiplier

then

7x = A's present age

and

5x = B's present age

:

Adding 10 yrs to their age produces a ratio of 9:7, there

=

Let the age of Sonal be `7x` yrs

And the age of Manoj be `5x` yrs

Ten years later their ages will be (7x + 10) and (5x + 10)

Given the ratio of the ages after 10 years = 9:7

Assume the ages as 9x and 7x

∴

And the present age of Manoj = 5x = 5×5 = 25 years
