A trader mixes 25% kerosene to his petrol and then he sells the whole mixture at the price of petrol. if the cost price of kerosene be 50 % of the cost price of petrol, what is the net profit percentage ?
-
- 11 1/9 %
- 12 1/9 %
- 9 1/11 %
- 20 %
Correct Option: A
K = 1 litre, price of K = 1
P = 4 litre price of P = 2
price of total (new) mixture = 1 X 1 + 4 X 2 = Rs. 9
price of pure petrol of same quantity = 5 X 2 = Rs. 10
Percentage profit = [(10-9) / 9] x 100 = 111/9 %
