Concept:The net effect of a markup followed by successive discounts is found by multiplying the respective multipliers. A multiplier less than 1 indicates a loss, while greater than 1 indicates a profit.
Explanation:First, find the net multiplier from the given percentages. Markup of 35% gives a multiplier of 1.35. A 20% discount gives a multiplier of 0.80, and a 10% discount gives 0.90. Multiply them:
1.35×0.80×0.90=0.972. This means the final selling price is 97.2% of the cost price. Since 97.2% is less than 100%, there is a loss of
100%−97.2%=2.8%.
You can also verify with actual numbers. Cost Price (CP) = ₹3500. Marked Price (MP) = ₹3500 + 35% of ₹3500 = ₹4725. After first discount of 20%, price becomes ₹4725 × 0.80 = ₹3780. After second discount of 10%, Selling Price (SP) = ₹3780 × 0.90 = ₹3402. Loss = CP − SP = ₹3500 − ₹3402 = ₹98. Loss percentage = (98/3500) × 100 = 2.8%.
Answer:Loss of 2.8% (Option C).
