Answer 2

Here we have to find the average of first four multiples of 5

First four multiples of 5 are 5, 10, 15, 20

sum of first four multiples = 5 + 10 + 15 + 20

                                          = 50

total numbers = 4

Now, to find the average we have to divide the sum of numbers by total numbers

Average = sum of numbers/total numbers

              = 50/4

             = 25/2 ( divided by 2)

Hence, the average of the first four multiples of 5 will be 25/2

So, option c is the correct answer
