Question

cofee costing rs 250 per kg was mixed with chicory costing rs 75 per kg in the ratio 5:2 for a certain blend . if the mixture was sold at rs 230 per kg,find the gain or loss percent ​

Answer 1

Answer:

The gain is 15 per cent

Step-by-step explanation:

Cost of coffee in Rs. per kg = 250

Cost of chicory in Rs. per kg = 75

Ratio of mixture of coffee and chicory is 5:2

Now,

In a mixuture of 7 kg, there will be 5 kg of coffee and 2 kg of chicory

Cost of 5 kg of coffee in Rs. = 250 * 5 = 1250

Cost of 2 kg of chicory in Rs. = 75 * 2 = 150

Cost of 7 kg of mixture in Rs. = 1250 + 150 = 1400

Cost of 1 kg of mixture in Rs. = 1400/7 = 200

CP = Cost price of 1 kg of mixture in Rs. = 200

SP = Selling price of 1 kg of mixture in Rs. = 230

As SP > CP, there is a profit

Profit = SP - CP

         = 230 - 200

         = 30

The seller makes a profit of Rs.30 per kg

Profit% = 100*(Profit / CP)

            = $100*\frac{30}{200}$

            = $\frac{30}{2}$

            = 15

The seller makes a profit of 15 per cent
