Q:

The average age of Vishal and Raghavendra is 24 years. If a new person Veerender is also included, the average age is increased by 1.5 years. What is the age of Veerender?

A) 28.5 yrs
B) 29.5 yrs
C) 30.5 yrs
D) 27 yrs

Answer:   A) 28.5 yrs 

Explanation:

According to the given data,
(V + R)/2 = 24
Now, after joining of Veerender,
V + R + D)/3 = 25.5

Hence, Veerender Age = 3(25.5) - 2(24) = 76.5 - 48 = 28.5 years.
