The image contains a data interpretation (DI) question in Hindi related to mobile phones sold by three shops (A, B, and C) across two different years (2020 and 2021). The question asks to determine the percentage of mobile phones sold by shop C in 2021 and by shop B in 2020.

Here's a quick breakdown of the problem:

### Given Information:
- In 2020, the ratio of mobiles sold by B and C in 2021 is 7:4.
- The total mobile phones sold by C in 2021 is 50% more than those sold by C in 2020.
- Shop B sold 10% more mobiles in 2021 than shop A sold in 2021.
- In 2020, C sold 50 phones.
- B sold 11.11% of the total mobiles in 2021.
- The total number of phones sold in both years combined is 65.

### Question:
You need to find the percentage of mobiles sold by C in 2021 and by B in 2020.

### Steps for Calculation:
1. **Calculate mobiles sold by C in 2020:**
   Since C sold 50 mobiles in 2020, the number of mobiles sold by C in 2021 is 50% more. Therefore, in 2021, C sold:
   \[
   50 + 0.5 \times 50 = 75 \text{ mobiles}
   \]

2. **Calculate mobiles sold by B in 2021:**
   We know B sold 11.11% of the total phones in 2021. The total number of phones sold in both years is 65. If B sold 11.11% in 2021, we need to determine how many that is. However, we don't have enough information directly yet, so this needs a bit more calculation based on other given data.

3. **Determine ratio relationships and solve for total mobiles:**
   Use the ratios provided between sales of mobiles by A, B, and C to deduce the overall percentages for each.
