Question

An average score of a studentin two papers is 50 and in three other paper is 75.what is the average of marks of the student in all five papers

Answer 1

Solution:-
average marks scored in two papers = 50
So, the total marks scored in these two papers = 50 × 2 = 100 marks
average marks scored in other three papers = 75
So, the total marks scored in these three papers = 75 × 3 = 225 marks
Total marks scored in all the five papers = 100 + 225
= 325 marks
then, the average marks scored in all the five papers = 325/5
= 65 marks  Answer.
