Answer 2

Answer:

Let the present age of Supriya and Neetu be 5x and 7x years respectively.

After two years, Supriya's age = 5x + 2

After two years, Neetu's age = 6x + 2

Therefore, the ratio of their ages after two years

= 5x + 2

6x + 2

This is given to be 6:7

Therefore, 5x + 2 = 6

6x + 2 7

Cross multiplication gives

6 (6x+2) = 7 (5x+2)

or, 36x + 12 = 35x + 14

or, 36x-35x = 14 - 12

or, x = 2

Therefore, Supriya's present age =5x=5×2=10

& Neetu's present age = 6x = 6× 2 = 12 years
