Answer:

(4) 25 years.

Step-by-step explanation:

The avg.age of Mahes and Deepak = 13 years.

So ages of Mahes + Deepak = 13×2 years

= 26 years .-----(i)

Similarly,

Ages of Deepak + Arati = 20×2

= 40 years.------(ii)

And

Ages of Ages of Arati + Mahes = 36-----------(iii)

Now,

(ii)- (i)=> Age of Arati - Age of Mahes=14years--(iv)

(iii)+(iv)=> 2× age of Arati =50 years

=> Age of Arati =(50÷2) years

Hence Age of Arati = 25 years.
