CORRECT QUESTION

The age of sonal and manoj are in the ratio 7 : 5 10 years hence the ratio of their ages will be 9:7

TO FIND

Find their present ages

SOLUTION

✹ LET the present age of Sonal be 7x and Manoj be 5x

**According to the given condition**

✹ After 10 years

Sonal's age = 7x + 10
Manoj's age = 5x + 10

➨ 7x + 10/5x + 10 = 9/7

➨ 7(7x + 10) = 9(5x + 10)

➨ 49x + 70 = 45x + 90

➨ 49x - 45x = 90 - 70

➨ 4X = 20

➨ x = 20/4 = 5

Hence,

Present age of Sonal = 7x = 7*5 = 35year

Present age of Manoj= 5x = 5*5=25 year
