The weights (in Kg) and their frequency distribution of 100 students are given below. Find their arithmetic mean.

Find the median and mode of the weights (in kg) of 100 students, the frequency distribution of which is given in question number 14 in exercise -1.

In a class with a certain number of students, if one student weighing 50 kg is added then the average weight of the class increases by 1 kg. If one more student weighing 50 kg is added, then the average weight of the class increases by 1.5 kg over the original average. What is the original average weight (in kg) of the class? (a) 2 (b) 4 (c) 46 (d) 47

The average weight of 100 students is 32 kg. The average weight of first 49 students is 30 kg and that of last 50 students is 34 kg. What is the weight (in kg) of the 50th student?
