Question
A person purchased petrol and kerosene oil for Rs.62 per
litre and Rs 55 per litre respectively. In what ratio should petrol be mixed with kerosene oil so that after selling the mixture at Rs.72.50/litre he may get a profit of 25 %?Solution
Selling price of mixture = Rs. 72.50/litre Profit = 25% So, cost price of mixture = 72.50 × (100/125) = Rs. 58/litre Now, Cost price of petrol = Rs. 62/litre Cost price of kerosene oil = Rs. 55/litre Using alligation, Required ratio of petrol and kerosene oil = (58 – 55) : (62 – 58) = 3 : 4 Therefore, petrol and kerosene oil should be mixed in the ratio 3 : 4.
