    Answer :

    Given

    • total number = 20
    • Average of total number = 100

    To find

    • Sum of numbers

    Solution

    Now,

    • Average = sum of observations/ total number of observations

    → 20 = sum of observations/ 100

    → Sum of observations = 100 × 20

    Sum of observations = 2000

    Therefore, the sum of numbers is 2000 and option d) is correct.

    average=(sum of no.) /total no.

    100=sum of no. /20

    sum of no. =100*20

    sum of no. =2000
