Question

The information below is about three sellers who sold two types of rice, brown and white. The quantity of white rice sold by all three sellers is 230 kg. The quantity of brown rice sold by B is 20% more than the quantity of white rice sold by A. The quantity of white rice sold by B is 20 kg more than that of brown rice. The ratio of brown rice sold by A to B is 2:3. The average quantity of brown rice sold by all three sellers is 60 kg, and the total rice (white and brown) sold by C is 75 kg. Question: The total quantity of white rice sold by C is how much more or less than the quantity of brown rice sold by A (in kg)?

Accepted Answer

15. From the average brown quantity, the total brown rice is 180 kg. Using the ratio of brown rice of A to B as 2:3 and the relation between B's brown and A's white, we can determine the individual quantities. Then C's white rice is compared with A's brown rice, giving a difference of 15 kg.
