In an examination, a pupil’s average marks were 63 per paper. If he had obtained 20 more marks for his Geography paper and 2 more marks for his History paper, his average per paper would have been 65. How many papers were there in the examination?
Solution
Let number of papers be $$x$$ and total marks in all papers = $$63x$$
According to ques,
=> $$\frac{63x+20+2}{x}=65$$
=> $$63x+22=65x$$
=> $$2x=22$$
=> $$x=\frac{22}{2}=11$$
=> Ans - (D)
