For a candidate to pass an examination, he must score 60% marks. If he scored 345 and failed by 15 marks, then what are the total marks for the examination?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 600.
Calculations:
Let the total marks of the examination be 100x.
Passing marks = 60% of 100x = 60x
According to the question;
⇒ 345 + 15 = 60x
⇒ 60x = 360
⇒ x = 60
Hence, total marks = 100x = 100 × 60 = 600
