1. Total questions = 50
Number of questions answered correctly = 47
Number of questions answered incorrectly = Total+Questions+-+Number+Of+Questions+Answered+Correctly = 50+-+47 = 3
Percentage of Randy answered incorrectly = Number+Of+Questions+Answered+Incorrectly%2FTotal+Questions x 100% = 3%2F50 x 100% = 6%
Therefore, answer is d.6% .
2. Total questions = 100
Number of questions answered correctly = 83
Percentage of Jack got right = Percentage of Jack answered correctly = Number+Of+Questions+Answered+Correctly%2FTotal+Questions x 100% = 83%2F100 x 100% = 83%
Therefore, answer is a.83% .
