Show answer & explanation
Correct answer: B
Solution:
Compute profit per kilogram: Selling price per kg = 10 × 6 = Rs 60; cost price per kg = Rs 40; profit per kg = 60 − 40 = Rs 20.
Find profit per corn: Profit per corn = 20 ÷ 6 = 10/3 (≈ Rs 3.33).
Number of corns needed to earn Rs 150: 150 ÷ (10/3) = 150 × 3/10 = 45.
Check: 45 × (10/3) = 150, so selling 45 corns gives the required profit.
Answer: He should sell 45 corns.
