A person's salary was decreased by 50% and subsequently increased by 50%. BY what much per cent does his salary increase or decrease?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Decrease 25%
Calculations:
Let the initial salary be Rs 100
According to the question:
Salary was increased by 50%
New salary = 150% of 100 = Rs 150
Now, the salary is decreased by 50%
Final salary = 150 × 50% = 75
The required decreased in salary = 100 - 75 = 25
Hence, required percentage = (25/100) × 100 = 25%
