The average age of a group of 15 employees is 24 years. If 5 more employees join the group, the average age increases by 2 years. Find the average age of the new employees. Correct Answer 32

The average age of a group of 15 employees is 24 years. Therefore, the sum of the ages of all 15 of them = 15 * 24 = 360 When 5 more employees join the group, the average age increases by 2 years. New average = 26. Now, there are 20 employees. Therefore, the sum of the ages of all 20 of them = 20x26 = 520 Therefore, the sum of the ages of the 5 new students who joined = 520 - 360 = 160 And the average age of each of the 5 new students = 160/5 = 32 years.
