Question

The average of 5 numbers is 8 sum of the first three is 30 what is the sum of the last two​

Answer 1

Answer:10

Step-by-step explanation:

let us take the numbers as a,b,c,d,e

avg of a,b,c,d,e = 8

a+b+c = 30

now the sum of a,b,c,d,e = 8*5 = 40

therefore d + e = (a+b+c+d+e) - (a+b+c)

                        = 40 - 30

                        = 10
