Question
In an exam, 4 children named A, B, C and D got the following percentage scores:A got 46%, B got 60%, C got 50% and D got 54%. The paper had a total of 50 questions with each question carrying equal marks.How many students among A, B, C and D got at least 26 questions correct?Note: There is no negative marks for incorrect attempts
Solution
To solve this problem, we first need to determine how many questions each student answered correctly. We do this by multiplying the total number of questions by the percentage each student got correct.
- For student A: 50 questions * 46% = 23 questions
- For student B: 50 questions * 60% = 30 questions
- For student C: 50 questions * 50% = 25 questions
- For student D: 50 questions * 54% = 27 questions
Now, we need to determine how many students answered at least 26 questions correctly.
Looking at the numbers above, we can see that student B answered 30 questions correctly, student C answered 25 questions correctly, and student D answered 27 questions correctly.
Therefore, the students who answered at least 26 questions correctly are B and D. So, the answer is 2 students.
