The average age of 8 men is increased by 2 years when two of them whose ages are 21 years and 23 years are replaced by two new men . The average age of the two new men is :
Total age increased = (8 x 2 ) years = 16 years.
sum of ages of two new men = (21 + 23 + 16) years = 60 years.
`:.` Average age of two new men = `(60/2)` years = 30 years.
