Answer 2

Answer: 25 years

Step by step explanation:

Let Ravi's present age be x.

Let his father's age be y years.

As per the question,

x = 1/2 y or 2x = y.. (1)

After 5 years,

Ravi's age = x + 5

Father's age = y + 5

As per the next condition,

$\tt \frac{x \: + \: 5}{y \: + \: 5} = \frac{6}{11}$

From (1),

$\tt\frac{x \: + \: 5}{2x \: + \: 5} = \frac{6}{11}$

11x + 55 = 12x + 30

x = 25

Thus, Ravi's present age = 25 years.
