In an examination, 78% of the total students who appeared were successful. If the total number of failures was 176 and 34% got first-class out of total students, then how many students got first class?
A272
B240
C112
D210
Answer:
A. 272
Read Explanation:
Students who failed = (100 – 78)% = 22%
22% of total students = 176
total students = (176/22)x100 = 800
34% of total students = 8 × 34 = 272
