A’s salary increases by 60% and then decreases by 30%. On the whole, A’s salary is increased by ______?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 12%.
Let A’s original salary be 100 units.
Increase by 60%:
New salary = 100 + 60 = 160
Decrease by 30%:
30% of 160 = 48
Final salary = 160 − 48 = 112
Overall increase = 112 − 100 = 12 %
