Answer 1

Answer:

68

Step-by-step explanation:

Let the numbers be numbers be 14 16 18 20 22.

sum - 90

biggest number - 22(has to be removed)

sum of remaining numbers - 68

Answer 2

Answer:

let the no. be

2x-4,2x-2,2x ,2x+2,2x+4

on adding them we get 90

so.

10x=90

X= 9

now no. will be

14,16,18,20,22

now greatest no. is 22

so removing it ..

we need to find the average of

14,16,18,20

average is

= (14+16+18+20)/4

= 68/4

= 17 answer..
