138 questions right and 12 questions wrong
45 were correctly answered
A test score of "90" represents the percentage of correct questions. Multiply this percentage by the total number of questions and you will have the number of questions correctly answered. Subtract this from the total to find answers wrong. 90% of 40 questions = .90 x 40 = 36 questions right. 40-36 = 4 answers wrong.
You would need to answer 68 questions correctly.

Divide how many questions you got right (11) by how many questions total there was (14). Then multiply it by 100. 11/14=0.78....... 0.78 x 100=78 YOUR ANSWER IS 78%

Getting 72 per cent right means if you had 100 questions you would have got 72 correct. Since there were half as many questions (50), you would have got half as many (36) correct.

Correctly answer 39 out of 46 questions
Designate the number of correctly answered questions as r. From the problem statement, r = 92 % of 28 = 0.92(28) = 25.76. If partial credit is allowed, this probably means that there were 25 questions completely right and one more that was considered three-fourths right.
