Accepted Answer

The monthly expenditure of the households of a ward of municipality is given in the following data:

Monthly expenditure No.of people

$501 - 750$ $75$

$751 - 1000$ $125$

$1001 - 1250$ $200$

$1251 - 1500$ $150$

$1501 - 1750$ $230$

$1751 - 2000$ $180$

$2001 - 2250$ $120$

$2251 - 2500$ $60$

$2501 - 3000$ $55$

Here, to draw the histogram, consider monthly expenditure on $X - axis$ and number of households on $Y - axis$ .
Using the bars(rectangle), mark the number of households of the corresponding expenditure.

To draw the frequency polygon, consider the mid-points of the histogram and join all the points starting from origin.

The histogram and frequency polygon of the above data is given below:

Age group	Number of people.
$15 - 25$	$25$
$26 - 35$	$30$
$36 - 40$	$27$
$41 - 50$	$18$
$51 - 55$	$47$
$56 - 60$	$20$
$61 - 75$	$6$
$76 - 90$	$2$

Marks	Number of students.
$0 - 10$	$6$
$10 - 20$	$14$
$20 - 30$	$25$
$30 - 40$	$35$
$40 - 50$	$46$
$50 - 60$	$51$
$60 - 70$	$32$
$70 - 80$	$24$
$80 - 90$	$7$
$90 - 100$	$2$
