Answer:

Class mark =2 lower limit+upper limit

Thus, lower limit + upper limit =35 ....(1)

and Class interval =  upper limit − lower limit

Thus, upper limit − lower limit =5 .....(2)

Adding (1) and (2), we get

2 (upper limit) =40

Upper limit =20

Hence, lower limit =15

Thus, class interval is 15−20.
