Question

if the average of 20 numbers is 100.then find the sum of numbers

Answer 1

We know that,

Average = Sum of observation / No. of observation

100 = Sum of numbers / 20

=> Sum of numbers = 100 × 20

= 2000

Answer 2

Hola Friend ✋✋✋

$average \: = \frac{sum \: of \: observations}{total \: number \: of \: observations } \\ \\ 100 = \frac{sum \: of \: numbers}{20} \\ \\ sum \: of \: numbers = 2000$

Hope it helps
