400 guavas were bought at ₹1240 per hundred and were sold at a profit of ₹940. Find the selling price (in ₹) per dozen of guavas.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 177
CP per 100 = ₹1240
CP of 400 = 4 × 1240 = 4960
Profit = ₹940
SP of 400 = 4960 + 940 = 5900
SP per guava = 5900 ÷ 400 = 14.75
SP per dozen = 14.75 × 12 = 177
