Question
A candidate just passed by getting 25 answers correct by
attempting 60 of the total questions. Find the total number of questions in the examination if a candidate needs 20% marks. (All questions carry equal marks)Solution

100 20 =Â
100 x = 125 Alternate method Given that 25 ≡ 20% 1 ≡Â
% 125 ≡ 100%
total number of questions = 125
