Question

The average of 5 numbers is 20. If we eliminate one number from it, the average will be reduced by 5, what is the number eliminated?​

Answer 1

Answer:

The eliminated number is 40

Step-by-step explanation:

Let the five numbers be a,b,c,d,e

a+b+c+d+e ÷ 5 = 20

a+b+c+d+e = 100

Let us remove e.

a+b+c+d ÷ 4 = 15

a+b+c+d = 60

Put this in first equation,

Then, 60 + e = 100

e = 40.
