Answer 2

Answer:

50

Step-by-step explanation:

let the sum of the eight numbers = x

so x/8 = 25

x = 200

when every number is multiplied by two the total sum is equal to twice the original total sum

2x = 2(200)

new sum = 400

now mean of this = 400/8 = 50

OR

x/8 = 25

when every number is multiplied by two the total sum is equal to twice the original total sum

let z be the new mean

2x/8 = z

2*25 = z  ( as we know x/8 = 25)

50 = z
