Given:
Initial average age of group = A
Total men = 22
Average age decrease = 2 years
Average age of the two old men = 58 years
Formula Used:
Total age of group before replacement = 22 × A
Total age after replacement = 22 × (A - 2)
Solution:
Total age decreased = 22 × 2 = 44 years
Age of two old men = 58 × 2 = 116 years
Age of two new men = 116 - 44 = 72 years
Average age of two new men = 72 ÷ 2 = 36 years
