In an exam, 65% of the students passed in English, 55% passed in Maths and 15% failed in both. If 245 students passed in both subjects, how many students took the exam?
A. 750
B. 800
C. 650
D. 700
A. 750
B. 800
C. 650
D. 700
Best answer
Answer: D. 700
Answer: (D) 700
Passed in at least one = 100 − 15 = 85%.
Passed in both = 65 + 55 − 85 = 35%.
35% = 245, so total = 245 × 100 ÷ 35 = 700.
