Question

A shopkeeper mixes 80 kg sugar worth of Rs. 6.75 per kg with 120 kg of sugar worth of Rs. 8 per kg. He earns a profit of 20% by selling the mixture. He sells it at the rate.

• A. Rs. 7.50 per kg
• B. Rs. 9 per kg
• C. Rs. 8.20 per kg
• D. Rs. 8.85 per kg

Answer 1

Answer: (B)

Rs. 9 per kg

Total cost $=80\times 6.75+120\times 8=Rs.1500$
Selling price $=1500\times \frac{120}{100}=Rs.1800$
S.P. per kg $=\frac{1800}{200}=Rs.9$
