Solution

Let's break down the problem step by step:

  1. Let's assume the number of students appeared from school 'P' is 100 (for simplicity). According to the problem, 70% of them qualified, so 70 students qualified from school 'P'.

  2. The number of students appeared from school 'Q' is 30% more than from school 'P'. So, 100 + 30 = 130 students appeared from school 'Q'.

  3. The number of students qualified from school 'Q' is 50% more than the students qualified from school 'P'. So, 70 + 35 = 105 students qualified from school 'Q'.

  4. Now, we need to find the percentage of students qualified to the number of students appeared from school 'Q'. The formula to calculate this is (Number of students qualified / Number of students appeared) * 100.

  5. Substituting the values into the formula, we get (105 / 130) * 100 = 80.76%.

So, the percentage of students qualified to the number of students appeared from school 'Q' is 80.76%.
