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

lutik1710 [3]

Answer: 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

$=100x+\frac{20}{100}\times100x\\=100x+20x\\=120x$

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

$=120x-\frac{20}{100}\times120x\\=120x-24x\\=96x$

On comparing it to the original size , we get

$\frac{96x}{100x}\times100=96\%$

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