The average age of 8 persons in a committee is increased by 2 years when two men whose gases are 35 years and 45 years are replaced by two women. The average age of two women is (in years)
Let the average age of the women be A years.
Total of their ages = 2A
Total of the eight persons = ET
When replaced (ET - 80 + 2A)/8 = ET/8 + 2
2A - 80 = 16
A = 96/2 = 48
