The average age of the men is 24.7, and the average age of the women is 25.9
The average age of all the employees is 25.5
Take no of men = x & no of women = y
24.7 x + 25.9 y = 25.5 (x+y)
24.7 x + 25.9 y = 25.5 x + 25.5 y
0.4 y = 0.8 x
\(\frac{y}{x}\) = \(2\)
So there are twice the no of women than men. So % of women will be 66.66%
Qt A = 66.67%
Qt B > QT A
Answer B
The average age of all the employees is 25.5
Take no of men = x & no of women = y
24.7 x + 25.9 y = 25.5 (x+y)
24.7 x + 25.9 y = 25.5 x + 25.5 y
0.4 y = 0.8 x
\(\frac{y}{x}\) = \(2\)
So there are twice the no of women than men. So % of women will be 66.66%
Qt A = 66.67%
Qt B > QT A
Answer B

Average age of all employees = 25.5
Average age of men = 24.7
Average age of women = 25.9
Difference in average age of men and all employees = 0.8
Difference in the average age of women and all employees = 0.4
\(\frac{Men}{Women} = \frac{1}{2}\) ......................[0.8M = 0.4W]
Women = \(\frac{2}{(1+2)}(100)% = 66.67%\)
Col. A: \(66.67%\)
Col. B: \(75%\)
Hence, option B
