Question

The ages of Sonu and Monu are in the ratio 7 : 5 . Ten years from now the ratio of their ages is 9 :7 . Find their present age.

Answer 1

Answer:

hello

present age of sonu= 7x

                         monu= 5x

10 years from now sonu= 7x+10

                              monu=  5x+10

7x+10=9

Step-by-step explanation:

Answer 2

Answer:

Sonu 35 years

Monu 25 years

Step-by-step explanation:

Present ages

Multiplying the ratio by x

Sonu's age=7x

Monu's age=5x

Ten years later

Sonu's age=7x+10

Monu's age=5x+10

Ratio is given as 9:7

Thus

$\frac{7x + 10}{5x + 10 } = \frac{9}{7}$

49x+70=45x+90

49x-45x=90-70

4x=20

x=5

Thus Sonu's present age=7×5

=35 years

Monu's present age=5×5

=25 years
