Answer 1

75-79 is modal class

Answer 2

the modal class is 74.5-79.5

because it is the highest frequency in the frequency column.

the median class is 69.5-74.5 because

n=200

n/2=200/2=100

and in the median class we see the cumulative frequency just more than the value of n/2.

the cumulative frequency of the class preceding the median class is 44.

the class interval to calculate median is 5.
