Question 998777
.
The sum of scores for first class:
18*84=1512
.
LOWEST POSSIBLE AVERAGE:
If average of second class=0, sum of scores for second class:
24*0=0
And combined average:
(1512+0)/42=36
The lowest average will be 36.
.
HIGHEST POSSIBLE AVERAGE:
If the average of the second class=100, sum of scores for second class:
24*100=2400
And combined average:
(1512+2400)/42=93.14
The highest average will be 93.14
.
So the possible average range will be:
{{{36}}} < {{{Average}}} < {{{93.14}}}
.
So the correct answer is (C).
