Question

Let

Answer 1

Answer:

I. Roshan, R = 25 years.

II. Ravi, Ra = 30 years.

Explanation:

Let the age of Roshan be R

Let the ages of Ravi be Ra

Given the following data;

R + Ra = 55

Ratio of their ages = 5:6 = 5 + 6 = 11

To find the age of R;

$R = \frac {5}{11} * 55$

$R = \frac {275}{11}$

Roshan, R = 25 years.

To find the age of Ra;

$R = \frac {6}{11} * 55$

$R = \frac {330}{11}$

Ravi, Ra = 30 years.
