Question
Average age of 10 boys is increased by 6 years when two
of them whose age are 18 and 22 years are replaced by two new members. What is the average age of the new member? TYPE RSolution
Let the sum of the age of two new members be ‘a’. Let the initial average age of boys = x After increment the average age of boys = x + 6 According to question, => 10x – 18 – 22 + a = 10(x+6) => a = 100 Average age of the new members = 100/2 = 50
