Question

The ratio of present ages of Virat and Sachin is 5 : 9. Three years hence ratio of their ages will be 3 : 5. Find Virat's present age?​

Answer 1

Step-by-step explanation:

the present age of virat is 5x

and the present age of sachin is 9x

after three year

age of virat is 3+5x

age of sachin is 3+ 9x

$\frac{3 + 5x}{3 + 9x} = \frac{3}{5} \\ = > 5(3 + 5x) = 3(3 + 9x) \\ = > 15 + 25x = 9 + 27x \\ = > 27x - 25x = 15 - 9 \\ = > 2x = 6 \\ = > x = 3$

hence the present age of virat is 5×3=15 years
