Answer: 19%


SOLUTION 1 :

Given:

Percentage of marks in English  = 36÷50

                                                    = (36÷50) x 100

                                                    =  0.72 x 100

                                                    = 72%

Percentage of marks in mathematics = 91÷100

                                                           = (91÷100) x 100

                                                           = 0.91 x 100

                                                           = 91%

Difference between percentage of maths and english =Highest value - lowest value

                                                                                                  =(91-72)%
