Correct Answer - Option 4 : 8

The logic followed is:

Let the age of Balu be “x” years.

Since Arjun is 4 years older than Balu.

Therefore, the age of Arjun = (x+4) years

Since Arjun is 4 years younger than Chandu, it means Chandu is 4 years older than Arjun

Therefore, age of Chandu = Age of Arjun + 4

= [(x + 4) + 4] years = (x + 8) years

Since Balu and Dinesh are twins

Therefore, age of Dinesh = age of Balu = x years

Difference between ages of Chandu and Dinesh = [(x + 8) - x] years = 8 years

Therefore, Chandu is 8 years older than Dinesh 

Hence, the correct answer is "8".
