A. 120
B. 200
C. 150
D. 180
Answer: Option C
Solution (By JKSSB Mock Tests)
Cost Price of 30 bananas = 5 * 5 = 25. Selling Price of 30 bananas = 6 * 6 = 36. Profit on 30 bananas = 11. Total profit is 55, which is 5 times 11. Total bananas = 30 * 5 = 150.
A grocer purchased 80 kg of sugar at Rs. 13.50 per kg and mixed it with 120 kg of sugar at Rs. 16 per kg. At what rate should he sell the mixture to gain 16%?
Explanation:
Total Cost = (80 * 13.50) + (120 * 16) = 1080 + 1920 = 3000. Total quantity = 200 kg. Cost Price per kg = 3000 / 200 = 15. Selling Price per kg for 16% gain = 15 * 1.16 = 17.40.
