Question Details

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.

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 WA, WB, and WC respectively.
Let the quantity of brown rice sold by sellers A, B, and C be BA, BB, and BC 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:
BB=1.2×WA

2. The ratio of brown rice sold by A to B is 2:3:
BABB=23BA=23BB

Substituting BB=1.2×WA into the ratio:
BA=23(1.2WA)=0.8WA

3. The quantity of white rice sold by B is 20 kg more than that of brown rice sold by B:
WB=BB+20=1.2WA+20

4. The average quantity of brown rice sold by all three sellers is 60 kg:
BA+BB+BC3=60BA+BB+BC=180

5. The total rice (white and brown) sold by C is 75 kg:
WC+BC=75WC=75-BC

6. The total quantity of white rice sold by all three sellers is 230 kg:
WA+WB+WC=230

Let us substitute WB and WC into this equation:
WA+(1.2WA+20)+(75-BC)=230
2.2WA+95-BC=2302.2WA-BC=135

From the brown rice equation:
BA+BB+BC=180
Substitute BA=0.8WA and BB=1.2WA:
0.8WA+1.2WA+BC=1802WA+BC=180BC=180-2WA

Now, substitute BC into the equation 2.2WA-BC=135:
2.2WA-(180-2WA)=135
4.2WA-180=135
4.2WA=315WA=3154.2=75 kg

Now we can compute the quantities for A, B, and C:

- For A:
WA=75 kg
BA=0.8×75=60 kg

- For B:
BB=1.2×75=90 kg
WB=90+20=110 kg

- For C:
BC=180-2(75)=30 kg
WC=75-30=45 kg

Now we analyze the requirements for seller D:

1. The total quantity of white rice sold by D (WD) is 5 kg more than the average quantity of brown rice sold by A and C:
Average of brown rice by A and C = BA+BC2=60+302=45 kg
Therefore, WD=45+5=50 kg

2. The ratio of brown rice sold by D and B is 11:15 respectively:
BDBB=1115
Since BB=90 kg:
BD=1115×90=11×6=66 kg

3. Find the total quantity of rice (brown and white) sold by D:
Total rice sold by D = WD+BD=50+66=116 kg

Thus, the correct answer is 116 kg.
