Correct Answer: 50%


Solution : Passing percentage = $\frac{\text{Number of students passed in the examination at all centres}}{\text{Total number of students appeared}}\times 100$
⇒ Passing percentage = $\frac{\text{20% of 25 + 30% of 30 + 35% of 40 + 40% of 45 + 50% of 60 + 75% of 100}}{25 + 30 + 40 + 45 + 60 + 100} × 100$
= $\frac{5 + 9 + 14 + 18 + 30 + 75}{300} × 100$
= $\frac{151}{300} × 100$
= $50.33\% \approx 50\%$
Hence, the correct answer is 50%.
