You increase the size of a computer screen display by 20%. then you decrease it by 20%. what is the size of the computer screen display now?

The size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.

Step-by-step explanation:

Let the original size of computer be 100x , then if it increases by 20 %

then the new size of the computer=100x +20% of 100x

The size of computer after 20% increase= 120x

If size of computer is decreased by 20 % then

The new size of computer= 120x - 20% of 120 x

On comparing it to the original size , we get

Thus, the size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.
