Elementary MathematicsPercentages
- A33.5%
- B30%
- C32%
- D35%
Explanation
Apply the discounts successively to ₹100: after 20% → ₹80; after 12.5% → 80×0.875 = ₹70; after 5% → 70×0.95 = ₹66.50. The total deduction is ₹33.50 on ₹100, i.e. 33.5%. Hence option (A) 33.5%. (Trap: simply adding the percentages gives 37.5%.)
