Question
In an examination, the percentage of students qualified to the students appeared from school 'P' is 70%.In school 'Q', the number of students appeared is 30% more than the students appeared from school 'P' and the number of students qualified from school 'Q' is 50% more than the students qualified from school 'P'.What is the % of students qualified to the number of students appeared from school 'Q' ?80.76%75.5%60.50%43%
Solution
Let's break down the problem step by step:
-
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'.
-
The number of students appeared from school 'Q' is 30% more than from school 'P'. So, 100 + 30 = 130 students appeared from school 'Q'.
-
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'.
-
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.
-
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%.
