Question

the averave age of 8 men increase by 2years when two of them whose ages are 20 and 24years are replaced by two women the age of two women is?

Answer 1

let average age of 8 men = x years

so, total age = 8x yrs.

two men's age = 20+24=44

total age of six men =8x-44

now say, two women's age = y yrs. 6men + 2 women, total age = 8x - 44+y

ATQ, (8x-44+y)/8= x+2

or, y=60
