• A. 300
• B. 400
• C. 500
• D. 600

Answer 1

Answer:

B. 400

If in an examination x% and y% candidates respectively failed in two different subjects while z% candidates failed in both the subjects, then the percentage of candidates who pass in both subject will be (100 + Z)- (x + y) Total number of students passed = (100 + 27) - (30+35) = 62% According to Question ; Total Students x 62/100 = 248 Total students = 400
