Question
The average age of a group of 5 men is 30 years. If one
man aged 35 leaves and a new person joins the group, raising the average age by 1 year, find the age of the new person.Solution
Sum of ages of 5 men = 5 × 30 = 150 years. After one man leaves, the sum of ages becomes 150 - 35 = 115 years. New average = 31 years, so the new total sum = 31 × 5 = 155 years. Age of new person = 155 - 115 = 40 years. Answer: a) 40 years
