The modal class for the following frequency distribution, is `{:("Marks:", 0-10,10-20,20-40,40-50,50-60,60-70,70-90,90-100),("No. of students:",4,6,14,16,14,8,16,5):}`A. 20-40B. 40-50C. 50-60D. 70-90 |

Answer» Correct Answer - B In the given frequency distribution the class intervals are not equal. So, we first adjust the frequencies taking 10 as minimum class interval as given below : `{:("Marks:", 0-10,10-20,20-30,30-40,40-50,40-50,50-60,60-70,70-80,80-90,90-100),("No. of students:",4,6,7,16,7,16,14,8,8,8,5):}` Since 40-50 is the class of maximum frequency. So, it is the modal class. |
