The age of Sohail, Afzal and Bilal are 17,16 and 12 respectively. If the age of Aslam also included the average of the ages is increased by 5. What is the age of Aslam?
Answer: 35
Explanation
The age of Sohail, Afzal and Bilal are 17,16 and 12 respectively. If the age of Aslam also included the average of the ages is increased by 5. What is the age of Aslam?
Average = 17 + 16 + 12/3
= 15 yrs
Given if Aslam added to them, their average increases by 5
=> Average of 4 members 15+5 = 20
What is the age of Aslam
20x4 = 80
15x3= 45
80-45 = 35
Hence, the age of Aslam is 35 yrs.
