Solution
Cost of 15 kg of dal at Rs.14.50 per kg= Rs.(15×14.50)= Rs. $217.5$Cost of 10 kg of dal at Rs.13 per kg= Rs. (10×13)= Rs.130Total amount of mixture =(10+15)=25 kg
Total cost of mixture= Rs.(217.5+130)= Rs.347.5
Selling price of 1 kg of mixture= Rs.15
Selling price of 25kg of mixture=Rs.(15×25)= Rs.375
Profit=Rs.(375−347.5)= Rs.27.5
Cost of 15 kg of dal at Rs.14.50 per kg= Rs.(15×14.50)= Rs. $217.5$
Cost of 10 kg of dal at Rs.13 per kg= Rs. (10×13)= Rs.130
Total amount of mixture =(10+15)=25 kg
Total cost of mixture= Rs.(217.5+130)= Rs.347.5
Selling price of 1 kg of mixture= Rs.15
Selling price of 25kg of mixture=Rs.(15×25)= Rs.375
