Question

Tanay is 9 yrs old. After 20 years of Tanay's birth what will be double of the sum of the ages of Tanay's cousin, who is currently 12 years old, and Tanay's sister, who is presently 14 years old?

Answer 1

At present,Tanay's age=9
Age of tanay's cousin= 12
Age of tanay's sister= 14
After 20 years of Tanay's birth,Tanay's age=20****(9+11)****
Age of tanay's cousin= 12+11=23
Age of tanay's sister= 14+11=25
After 20 years of Tanay's birth, double of the sum of ages of Tanay's cousin and Tanay's sister=2(23+25)=2(48)=96
