Question
In an examination of three papers of 200 marks each, a
candidate got 120 and 100 marks in the first two papers. The percentage of marks he should get in the third paper to have an aggregate of 62% is.Solution
Marks obtained in first two papers = 120 + 100 = 220 Marks obtained in three papers = 600 × (62/100) = 372 Required marks to be obtained in third papers = 372– 220 = 152 Require percentage of marks = 152*100/200 = 76%.
