Question

Krishna salary was decreased by 50% and subsequently increased by 50% how much percent did he lose.
quick

Answer 1

it is zero % because -50%+50%=0%

Answer 2

Let Krishna original salary be 100.


Given that his salary is decreased by 50% = 100 * 50/100 = 50.

Given that his salary is subsequently increased by 50% = 50 * 150/100 = 75.

Loss = 100 - 75 = 25.

Loss % = 25/100 * 100

             = 25%.


Hope this helps!
