Calculate Alok's Present Age

Alok's age in 20 years is given as 62 years. To find his present age, we subtract 20 years from his future age.

Alok's Present Age = Alok's Age in 20 years - 20 years

Alok's Present Age = $62 - 20 = 42$ years.

Use Age Ratio to Find Anil's Age

The ratio of the present ages of Alok and Anil is 3 : 4.

Let Alok's present age be $3x$ and Anil's present age be $4x$.

We know Alok's present age is 42 years.

Therefore, $3x = 42$.

Solving for $x$:

$x = \frac{42}{3}$

$x = 14$.

Determine Anil's Present Age

Anil's present age is represented by $4x$. Substitute the value of $x$ we found.

Anil's Present Age = $4 \times x$

Anil's Present Age = $4 \times 14$

Anil's Present Age = 56 years.
