Number of students	7	10	15	8	10

Draw the less than cumulative frequency curve(Ogive curve)

Answer 1

We are going to form less than frequency table

$Marks$	$No.ofstudents$	$c.f$
Less than $10$	$7$	$7$
Less than $20$	$10$	$17$
Less than $30$	$15$	$32$
Less than $40$	$8$	$40$
Less than $50$	$10$	$50$
