total number of questions answered = 36

percent = ?

Process

Let 40 question be the 100% and use proportions and cross multiplication to solve this problem

                     40 questions ------------------- 100%

                     36 questions -------------------  x

                     x = (36 x 100)/40

                    x = 90 %
