Correct answer: C

  • For a loss of L% on cost price: Selling Price (SP) = Cost Price (CP) × (1 − L/100), so CP = SP ÷ (1 − L/100).

  • For a desired profit of P% on cost price: required SP = CP × (1 + P/100).

  1. Cost price of 24 mangoes: CP = ₹400 ÷ (1 − 20/100) = ₹400 ÷ 0.80 = ₹500.

  2. Required total selling price for a 20% profit: SP = ₹500 × 1.20 = ₹600.

  3. Selling price per mango: ₹600 ÷ 24 = ₹25.

  4. Number of mangoes sold for ₹100 at ₹25 each: ₹100 ÷ ₹25 = 4.

Cross-check: selling 4 mangoes at ₹25 each returns exactly ₹100; the cost price per mango is ₹500 ÷ 24 ≈ ₹20.83, and (₹25 − ₹20.83) ÷ ₹20.83 × 100 ≈ 20%, confirming the intended profit margin.

Therefore, he must sell 4 mangoes to collect ₹100 at the required 20% profit.
