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?
Answer & explanation
Correct answer: option 3
Let total marks = 100x
Passing score = 60% of 100x = 60x
According to question ,
60x = 345 + 15 = 360
60x = 360
x = \(\frac{360}{60}\) = 6
So , Total Marks = 6 × 100 = 600
