Quantitative Aptitiude (CLAT) Average

A student on her first 3 tests receives on an average score of N points. If she exceeds her previous average score by 20 points on her fourth test, then what is the average score for the first 4 tests?

N + 20

N + 10

N + 4

N + 5

Explanation:

The average score of student in 3 tests is N points. Hence the total score = 3N points. Given the score in fourth test = N + 20, the average score of student in four tests will be = (3N +N+20)/4 = N+5
