Question

Alok is twice as old as Ashok. Five years ago, his age was thrice of Ashok's age. Then what is the present age of Alok?​

Answer 1

Given,

Alok is twice as old as Ashok.

5 years ago, his age was thrice of Ashok's age.

To find,

The present age of Alok.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Let, the present age of Ashok = x years

So, Present age of Alok = 2x years

5 years ago,

The age of Ashok = (x-5) years

The age of Alok = (2x-5) years

According to the data mentioned in the question,

(2x-5)/(x-5) = 3

2x-5 = 3x-15

3x-15 = 2x-5

3x-2x = 15-5

x = 10

Present age of Ashok = 10 years

Present age of Alok = 2×10 = 20 years

Hence, the present age of Alok is 20 years.
