Question
The salary of a worker is first increased by 25%, then
it is decreased by 12%. The percentage change in his salary is:Solution
Let the original salary be ₹100.
Increase by 25%: ₹100 + 25% of ₹100 = ₹100 + ₹25 = ₹125
Decrease by 12%:
₹125 − 12% of ₹125 = ₹125 − ₹15 = ₹110
Final salary = ₹110
Change = ₹110 − ₹100 = ₹10
Percentage change = (₹10 / ₹100) × 100 = 10% increase.
