Consider the frequency distribution of the hights of 60 students of a class

The sum of the lower limit of the modal class and the upper limit of the median class is

A

310

B

315

C

320

D

330

Text Solution

Verified by Experts

The class having maximum frequency is the modal class
So, the modal class is 150-155 Its lower limit is 150
Also,`N=60 rArr N/2=30` and the cumulative frequency just more than 30 is 37 . Its class is 160-165 , whose upper limit is 165
Required sum =(150+165)=315
