In a school 420 students appeared for Mathematics and English examination. Out of this 285 students passed in Mathematics, 290 students passed in English and 260 students passed in both the subjects, then how many students fail in both the subjects.

A) 105
B) 12
C) 135
D) 180

Correct Answer:

A) 105

Description for Correct answer:

Total number of students = 420

Passed in Mathematics = 285

Passed in English = 290

Passed in both the subjects = 260

Total number of passed students = 25 + 260 + 30 = 315

Number of students failed in both subjects = 420 - 315 = 105
