Read the following information carefully and answer the questions given below. The information about three sellers who sold two types of rice, i.e., brown and white.
The quantity of white rice sold by all three seller 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.
The total quantity of white rice sold by D is 5 kg more than the average quantity of brown rice sold by A and C. If the total quantity of brown rice sold by D and B is in the ratio of 11:15 respectively, then find the total quantity of rice (brown and white) sold by D.
Correct Answer :
116 kg
Solution :
Let us break down the given information step-by-step to find the quantities of rice sold by sellers A, B, C, and D.
Let the quantity of white rice sold by sellers A, B, and C be , , and respectively.
Let the quantity of brown rice sold by sellers A, B, and C be , , and respectively.
We are given the following relations:
1. The quantity of brown rice sold by B is 20% more than the quantity of white rice sold by A:
2. The ratio of brown rice sold by A to B is 2:3:
Substituting into the ratio:
3. The quantity of white rice sold by B is 20 kg more than that of brown rice sold by B:
4. The average quantity of brown rice sold by all three sellers is 60 kg:
5. The total rice (white and brown) sold by C is 75 kg:
6. The total quantity of white rice sold by all three sellers is 230 kg:
Let us substitute and into this equation:
From the brown rice equation:
Substitute and :
Now, substitute into the equation :
Now we can compute the quantities for A, B, and C:
- For A:
- For B:
- For C:
Now we analyze the requirements for seller D:
1. The total quantity of white rice sold by D () is 5 kg more than the average quantity of brown rice sold by A and C:
Average of brown rice by A and C =
Therefore,
2. The ratio of brown rice sold by D and B is 11:15 respectively:
Since :
3. Find the total quantity of rice (brown and white) sold by D:
Total rice sold by D =
