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?

400 480 600 540

600

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
