B=Smaller than the size you started with
C=Smaller than the size you started with
D=It depends on the original size.

Answer 1

B and C are the same choices but the computer size will stay the same as it was before.

Answer 2

C and D :Smaller than the size you started with

Explanation:

Hi, options c and d are the same.

If we increase the size of a computer screen display by 20% and then decrease it by 20%, the size of the computer screen display now is smaller than the size you started with.

For example, if the initial size is 100m, we increase the size by 20%.

100 x 1.20 = 120m

Then decrease the size by 20%:

120 x 0.80 = 96m

If we compare the actual size with the original size:

100m (original) > 96m (now)
