Question

Arun purchased 20 kg of chocolate at Rs. 68 per kg and mixed it with 30 kg of dark chocolate at Rs. 78 per kg. At what rate should he sell the mixture to gain 50 percent profit?

• A. Rs. 105
• B. Rs. 100
• C. Rs. 110
• D. Rs. 111

Answer 1

Answer:

D. Rs. 111

Total cost of 20 kg of chocolate = 20 × 68 = Rs. 1360 Total cost of 30 kg of dark chocolate = 30 × 78 = Rs. 2340 Total cost of two varieties of chocolate of 50 kg = 1360 + 2340 = Rs. 3700 Selling price at 50% profit = 3700 × (1 + 50%) = 3700 + 1850 = 5550 Selling price of chocolate per kg = 5550/50 = Rs. 111
