A student needs at least 60% to pass. He got 40% on the first exam, 70% on the second, and x% on the third (equal weightage).
What is the minimum x% to pass?
Show answer & explanation
Correct answer: A
Explanation
Passing Average = 60%
Three Exams (Equal Weightage): 40%, 70%, x%
Average = (Sum of Scores) / 3
(40 + 70 + x)/3 ≥ 60
110 + x ≥ 180
x ≥ 70
= 70%
