Directions: In the question below, the question is followed by five options. Read the information given in each option carefully and determine which of the following options, alone, is sufficient to find the answer. A farmer sold 6 bags of wheat and 9 bags of rice in a day. Determine the ratio of the cost price of one bag of wheat to one bag of rice (assuming the quantity of one rice bag is the same as that of one wheat bag).

If all the items are sold at the cost price of a wheat bag, the farmer earns a 30% profit.

If all the items are sold at the cost price of a rice bag, the farmer incurs a 15% loss.

The ratio of the total cost price of 6 bags of wheat to 9 bags of rice is 5 : 4.

The difference between the cost prices of one bag of wheat and one bag of rice is Rs. 250.

The sum of the cost prices of one bag of wheat and one bag of rice is Rs. 850, and the total cost price of all items sold in a day is Rs. 5,900.
