Options:
A . 23%
B . 33%
C . 18%
D . 38%
Answer: Option A Answer: (a) Let the total number of students = 100 Number of students who failed in Hindi or English or both = 52 + 42 – 17 = 77 Number of students who passed in both subjects = 100 – 77 = 23% Required percentage = 23 Using Rule 23, a = 52%, b = 42%, c = 17% Passed candidates = 100 – (52 + 42 – 17) = 100 – (94 – 17) = 100 – 77 = 23%
