Answer 1

Step-by-step explanation:

i ) Number of questions = 150

John got 80 % correct answers = 150 x 80 %

= ( 150 x 80 ) / 100

= 15 x 8 = 120

mohan got 64 % correct answers = 150 x 64 %

= ( 150 x 64 ) / 100

= ( 15 x 64 ) / 10

= ( 3 x 64 ) / 2

= ( 3 x 32) = 96

ii ) mohan percentage of correct answers : John percentage of correct answers

= 64 % : 80%

= 64 : 80

= 8 : 10

= 4 : 5
