Answer 2

The correct answer is - Ben is 8.

Since Ben is 4 times older than Ishaan, but also we know the fact that Ben is 6 years older than Ishaan, that leaves us with only one number as the possible solution, the number 8.

In order to get to the result we should find a number that multiplied by four and summed up with six, gives the same result.

4 x 2 = 8

2 + 6 = 8

Knowing now that the age of Ben is 8, we can also conclude that the number used for multiplying and summing, 2, is the number that represents the age of Ishaan.
