Explanation
Step 1: Identify the given information
Step 2: Find the percentage of students who passed
Since the total percentage of students must be 100%, we can find the passing percentage by subtracting the failed percentage from the total.
Percentage of passing students=100%−28%=72%
Step 3: Calculate the actual number of students who passed
Now, we find 72% of the total 175 students:
Number of passed students=10072×175
Let's simplify the equation by dividing 175 and 100 by 25:
Number of passed students=72×47
Number of passed students=18×7
Number of passed students=126
Correct Answer
The correct option is (b) 126.
