Question

A student answered 57 problems on a test correctly and received a grade of 95%. How many problems were on the test, if all the problems were worth the same number of points?

Answer 1

Answer:

number of correct/percentile

57/95

=57/0.95

=60

Answer 2

Step-by-step explanation:

Let the total number of questions in the exam be x

Then 95% of x = 57

95/100× x= 57

By Cross Multiply

x= 57×100/95

x=3×20 ( 100 and 95 are divided by 5 which result 20 and 19 respectively and again 57 is divided by 19 which gives 3)

x=60
