Step 1: Given Data
From the first graph, the total quantity of apples sold by seller A and seller B is:
- Seller A: 120 kg of apples
- Seller B: 90 kg of apples
Step 2: Calculate the total apples bought by each seller
- For Seller A:
Since 20% of the apples bought by seller A were rotten, 80% of the apples were sold. Therefore, the total quantity of apples bought by seller A is:
\[
\text{Total apples bought by A} = \frac{120}{0.80} = 150 \, \text{kg}
\]
- For Seller B:
Since 10% of the apples bought by seller B were rotten, 90% of the apples were sold. Therefore, the total quantity of apples bought by seller B is:
\[
\text{Total apples bought by B} = \frac{90}{0.90} = 100 \, \text{kg}
\]
Step 3: Find the ratio of apples bought by seller A and seller B
The ratio of apples bought by seller A to seller B is:
\[
\text{Ratio of apples bought by A and B} = \frac{150}{100} = 3:2
\]
Step 4: Conclusion
Thus, the ratio of the quantities of apples bought by fruit sellers A and B is 3:2. Therefore, the correct answer is (D).
