400 pears were bought at ₹1250 per hundred and were sold at a profit of ₹900. Find the selling price (in ₹) per dozen of pears.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 177.
Number of pears = 400
Cost per 100 pears = 1250
Total cost = (400 ÷ 100) × 1250 = 4 × 1250 = 5000
Profit = 900
Total selling price = 5000 + 900 = 5900
Selling price per pear = 5900 ÷ 400 = 14.75
Selling price per dozen = 14.75 × 12 = 177
