Question and options
A merchant made two types of mixed oils P & Q with three different types of oils, X, Y and Z in the ratios 3:2:5 and 4:3:3 respectively with the costs of each litre of X, Y and Z being ₹120, ₹125 and ₹150 respectively. How much profit will the merchant make if he sells 100 litres each of P and Q at the same rate of ₹136 per litre?
- ₹350
- ₹250
- ₹750
- ₹550
Answer and explanation
Correct answer: D - ₹550
P costs (3x120+2x125+5x150)/10 = 136 per litre; Q costs (4x120+3x125+3x150)/10 = 130.5 per litre. Selling both at 136: profit = 100x0 + 100x5.5 = Rs 550.
