Question

In a monthly test the marks obtained in mathematics by $16$ students of a class are as follows
$0,0,2,2,3,3,3,4,5,5,5,5,6,6,7,8$
The arithmetic mean of the marks obtained is

• A. $3$
• B. $4$
• C. $5$
• D. $6$

Answer 1

Answer: (B)

$4$

Since, Mean $=\frac{0+0+2+2+3+3+3+4+5+5+5+5+6+6+7+8}{16}$
$\Rightarrow$ Mean $=\frac{64}{16}$
$\Rightarrow$ Mean $=4$
$\therefore$ Option $B$ is correct.
