"In 2017
Let students appeared in exam A and exam B be 7c and 9c respectively.
Students appeared in exam C = 125% of 9c = 11.25c
So 7c + 9c + 11.25c = 2180
27.25c = 2180
c = 80
Students appeared in exam A = 560
Students appeared in exam B = 720
Students appeared in exam C = 900
In 2018:
Students appeared in exam A = 600 × 4 = 480
5
Students appeared in exam B = 560 × 2 – 480 = 640
Students appeared in exam C = 600
Total students appeared = 480 + 640 + 600 = 1720
Number of students cleared exam = 10% of 560 + 20% of 720 + 20% of 900 + 20% of 480 + 10% of 640 + 40% of 600 = 56 + 144 + 180 + 96 + 64 + 240 = 780
Hence, option B is correct."

Understanding the Data
In 2017 and 2018, we need to calculate the number of students who cleared exams A, B, and C based on the provided information.

2017 Data
- **Total Students**: 2180
- **Ratio of Students**: A:B = 7:9
- **Let**: A = 7x, B = 9x
- **Students in C**: C = B + 0.25B = 1.25B = 1.25(9x) = 11.25x
- **Equation**: 7x + 9x + 11.25x = 2180
- **Total**: 27.25x = 2180
- **Solving for x**: x = 80
- **Students Appeared**:
- A = 7(80) = 560
- B = 9(80) = 720
- C = 11.25(80) = 900
- **Students Cleared**:
- A cleared: 10% of 560 = 56
- B cleared: 20% of 720 = 144
- C cleared: 20% of 900 = 180
- **Total Cleared in 2017**:
- Total = 56 + 144 + 180 = 380

2018 Data
- **Average of A and B**: 560
- **Students in C**: 600
- **Total for A and B**: 2 * 560 = 1120
- **A + B = 1120, C = 600**
- **A:C Ratio**: 4:5
- **Let**: A = 4y, C = 5y
- **From C**: 5y = 600 → y = 120
- **Calculating A**: A = 4(120) = 480
- **Calculating B**: B = 1120 - A = 1120 - 480 = 640
- **Students Cleared**:
- A cleared: 20% of 480 = 96
- B cleared: 10% of 640 = 64
- C cleared: 40% of 600 = 240
- **Total Cleared in 2018**:
- Total = 96 + 64 + 240 = 400

Final Calculation
- **Total Students Cleared in 2017 and 2018**:
- 380 (2017) + 400 (2018) = 780
Thus, the answer is **option (b) 780**.
