Answer:

Correct Answer: C

Solution:

Number of females in C $ =4200\times \frac{35}{100}-2400\times \frac{33}{100} $ $ =1470-792=678 $ Number of females in $ D=4200\times \frac{15}{100}-2400\times \frac{12}{100} $ $ =630-288=342 $ Number of females in $ E=4200\times \frac{8}{100}-2400\times \frac{10}{100} $ $ =336-240=96 $

$ \therefore $ Required average $ =\frac{678+342+96}{3}=\frac{1116}{3}=372 $
