$40$
0%
$50$
0%
$20$
0%
$30$

Explanation

Classes -

$0-10, 10-20, 20-30, 30-40$

Count the tally marks

0%
$4$
0%
$5$
0%
$6$
0%
$3$

$5$ .

The size of the each class intervals is:

0%
$5$
0%
$0$
0%
$10$
0%
None of these

Explanation

The size of the each class intervals is the difference between the upper and lower limits of any class

$= 10-0 = 10.$

Range of

$14, 12, 17, 18, 16$ and

$x$ is

$20$ . Find

$x$

$(x > 0)$

0%
$2$
0%
$28$
0%
$32$
0%
Cannot be determined

Explanation

Let

$x$ be the highest no. and here lowest no. is

$12$
Since, Range

$=$ Highest value

$-$ Lowest value

$\therefore 20 = x - 12$

$\therefore x =32$

$\therefore$ Option

$C$ is correct.
