What is the mark????????

Question

A boy is taking his maths test. Both papers carry the same weightage. He scored 47/80 for his first paper. The second paper is out of 100. How many marks does he need to get at least 75% of the total mark, assuming that there is no half mark.

Answer 1

47/80 = 58.75%

 

58.75 + N

58.75 + N = 150

 

N = 91.25

 

He needs 92
