In an objective type paper of 150 questions; John got 80% correct answers and Mohan got 64% correct answers.

(i) How many correct answers did each get?

(ii) What percent is Mohan’s correct answers to John’s correct answers?

Answer 1

Total questions = 150
John got correct answers = 80%
Mohan got correct answer = 64%

(i) Number of correct answers got by John
= `(80)/(100) xx 150`
= 120

Number of correct answers got by Mohan

= `(64)/(100) xx 150`

= `(64)/(4) xx 6`

= 96

(ii) % of Mohan's correct answers to John's correct answers

= `(96)/(120) xx 100`

= `(4)/(5) xx 100`

= 4 x 20

= 80%
