Answer 1

hey!!!

What do we have to in this sum??

7 students brought 42 marks out of 50.
10 students brought 36 marks out of 50.
13 students brought 30 marks out of 50.
8 students brought 45 marks out of 50.
2 students brought 50 marks out of 50.

If u have to take out percentage so I'll take it out...

% of the first 7 students=
$\frac{42}{50} \times 100$
$= 84\%$

% of the 10 students:-
$\frac{36}{50} \times 100$
$= 72\%$

% of the 13 students:-
$\frac{30}{50} \times 100$
$= 60\%$
% of the 8 students:-
$\frac{45}{50} \times 100$
$= 90\%$
% of the 2 students:-
$\frac{50}{50} \times 100$
$= 100\%$

Hope it helps!!!...
