In Class XI of a certain school, there are 30 students in a Mathematics class and 20 students in Biolog class. Find the number of students which are in Mathematics class or in Biology class in the following cases: (i) Two classes are conducted at the same time. (ii) Two classes are condcuted at different time and 5 students study both the subject

While calculating mode the following observation are found. Lower limit of modal class =40, frequency of modal class =20, frequency of previous class =12 , frequency of preceding class =11 and width of the class =10, find mode .

The class marks of a frequency distribution are given as follows 15,20, 25,……….. The class corresponding to the class mark 20 is
