39-35 = 4.......39.....x (Distance from mean)

4 * 40 = x * 10
x = 16
Average score among female employees = 39 + 16 = 55

Tried an approach different from the traditional one: (30 second approach)

40 male have avg of 35 and the mean is 39.
Difference = 39-35 = 4
This difference of '4' has to be compensated by additional value of 10 elements(females)
so additional value * 10 = 4*40
additional value = 16

average age of females = mean + additional value= 39+16 = 55
--E--

Let me know if you have any query

We can let f = the average score among all female employees and calculate a weighted average:

[(35)(40) + 10f]/50 =39

(35)(40) + 10f = (39)(50)

35 x 4 + f = 39 x 5

140 + f = 195

f = 55

Answer: E

Mean of 50 employees is 39
Mean of 40 Male employees is 35
Mean of 10 Female employees is x

Now 39*50 = 35*40 + 10*x
1950 - 1400 = 10x
x=55
