In a test consisting of 120 questions, Anuradha answered 65% of the first 60 questions correctly. What percentage of the remaining questions does she need to answer correctly to score 75% in the test?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 85
To score 75%, the total number of question need to be correct = (120 × 75)/100 = 90
In the first 60 questions, the corrected answer percentage = (60 × 65)/100 = 39
Hence, the remaining number of questions, need to be correct = 90 - 39 = 51
Remaining questions need to attempt = 60
so, the corrected answer percentage should be = (51 × 100)/60 = 85%
