400 apples were bought at ₹1240 per hundred and were sold at a profit of ₹840. Find the selling price (in ₹) per dozen of apples.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 1 i.e. 174
Cost price of 400 apples = 4 × 1240 = 4960
Profit = 840
Selling price = 4960 + 840 = 5800
Number of dozens = 400 ÷ 12 = 33 1/3 dozens
Selling price per dozen = 5800 ÷ 33 1/3 = 5800 × 3/100 = 174
