# The average marks of 32 boys of the section A of class 10th is 60 whereas the average marks of 40 boys of section B of class 10th is 33. The average marks for both the sections combined together is:

The average marks of 32 boys of the section A of class 10th is 60 whereas the average marks of 40 boys of section B of class 10th is 33. The average marks for both the sections combined together is:
[A]$44$
[B]$45\frac{1}{2}$
[C]$45$
[D]$46\frac{1}{2}$

$45$
Required average $= \frac{32\times 60 + 33\times 40}{72}$
$= \frac{1920+1320}{72} = \frac{3240}{72} = 45$
Hence option [C] is the right answer.
