The Correct Option is C
Solution and Explanation
Let Barun’s age be \(10x.\)
Arun’s age is \(4x.\)
The difference of these ages is \(6x,\) a constant.
When Arun’s age is 50% of Barun’s age, this difference would also be 50%, i.e., Barun’s age at that stage would be \(12x.\) It would increase by 20%
