Question
John's salary was decreased by 50% and subsequently increased by 50%. How much percent does he lose?
Solution
Let's assume John's initial salary was $100.
-
After a decrease of 50%, his salary becomes 100 is 100 - 50).
-
Then, his salary is increased by 50%. However, this increase is not based on his initial salary, but on his current salary of 50 is $25.
-
Therefore, after the increase, his salary becomes 50 + 75).
-
To find out the percentage loss, we need to compare his final salary (100). The difference between these two amounts is $25.
-
To express this difference as a percentage, we divide it by the initial salary and multiply by 100. So, the percentage loss is (100) * 100 = 25%.
So, John has a loss of 25% of his initial salary.
