A75% increase followed by a 33 1/2% decrease

After 75% increase followed by a 33 1/2% decrease the net increased is 16.375%.

Solution:

Need to determine net percentage increase or decrease when a value is increased by 75% and then decreased by that is 33.5%.

Let’s assume initial value be represented by variable x.

Now there is decrease of 33.5%

Hence after 75% increase followed by a decrease the net increased is 16.375%.
