Answer:

5

Step-by-step explanation:

Let the numbers be x1 x2 ...... x12

Given

( x1 + x2 + ..... + x12 ) / 12 = 40

( x1 + x2 + ..... + x12 ) = 480

now each number is divided by 8

i.e x1/8 x2/8 ........ x12/8

if we add them we get

( x1 + x2 + ..... + x12 ) /8 = 60

Now the new mean is 60/12 = 5
