400 apples were bought at ₹1220 per hundred and were sold at a profit of ₹920. Find the selling price (in ₹) per dozen of apples.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 174.
Total apples = 400, Cost = ₹1220 per 100
Cost of 400 apples = 1220 × 4 = ₹4880
Profit = ₹920 → Selling price
= 4880 + 920 = ₹5800
Number of dozens = 400 ÷ 12 = 33
Selling price per dozen = 5800 ÷ (400 ÷ 12)
= 5800 ÷ (100/3) = 5800 × 3 ÷ 100 = ₹174
