Solve the 12th question please

Given:

The ratio of present ages of Sonu and Monu = 7:5

The ratio of their ages after 10 years = 9:7.

To find:

The present ages of Sonu and Monu.

Solution:

Let the present ages of Sonu and Monu are 7x and 5x respectively.

Their ages after 10 years are (7x+10) and (5x+10) respectively.

The ratio of their ages after 10 years = 9:7.

On further simplification, we get

Now,

Sonu's present age =

                                 =

                                 =

Monu's present age =

                                 =

                                 =

Therefore, the present ages of Sonu and Monu are 35 and 25 respectively.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
