Question

The ratio of Reeta's age and Site's age is 3:5 and the sum of their ages is 80 years. The ratio of their ages after 10 years will be

Answer 1

Answer:

Let Reeta's age be 'r' and Seeta's age be 's',

r:s = 3:5 (given)

=> r = 3x , s = 5x

r+s = 80 (given)

=> 3x + 5x = 80

=> 8x = 80

=> x = 10

=> r = 3x = 30, s = 5x = 50

After 10 yrs,

Reeta's age will be = r + 10 = 30 + 10 = 40

Seeta's age will be = s + 10 = 50 + 10 = 60

$\frac{r + 10}{s + 10} = \frac{40}{60} = \frac{2}{3}$
