Question
The marks obtained by 15 students out of a maximum of 25
in a test are given as 13, 11, 16, 15, 18, 12, 13, 14, 10, 22, 21, 20, 17, and 24. Find the sum of the modes of this set of data.   ÂSolution
In the given data. given 13 in two times and 15 too. So mode = 13 and 15 then the product of mode = 13+15 =28
