Question

The ages of mohan and and sohan are in the ratio 5:7. If mohan was 9 years older and sohan 9 yeats younger, then ththeir ages would be in ratio 2:1. Find their present ages.​

Answer 1

Answer:

the answer is 15 and 21 years

Explanation:

Let x be the present age of mohan and sohan then present age of mohan is 5x and that of sohan is 7x.

According to 1st condition -

Mohan's age will be 5x+9

Sohan's age will be 7x−9

⇒5x+9:7x−9=2:1

⇒

7x−9

5x+9

=

1

2

⇒(5x+9)=2(7x−9)

⇒5x+9=14x−18

⇒5x−14x=−18−9

⇒−9x=−27

⇒x=3

Present age of mohan is 5x=5×3=15

Present age of sohan is 7x=7×3=21

hence, solved.
