400 mangoes were bought at ₹1220 per hundred and were sold at a profit of ₹820. Find the selling price (in ₹) per dozen of mangoes.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 171.
Cost price of 100 mangoes = ₹1220
So, cost price of 400 mangoes = ₹1220 × 4 = ₹4880
Profit = ₹820
Selling price = ₹4880 + ₹820 = ₹5700
400 mangoes = 400 ÷ 12 = 33.33 dozens
Selling price per dozen = ₹5700 ÷ 33.33 = ₹171
