Answer / abhisek das
(C) Out of 14 questions 7 are correct and he requires 65%
to pass.
As per the question to qualify he has to answer rest all
questions correctly
Let there are ?X? questions left in the paper so he has to
answer all ?X? questions to qualify.
Hence,
(7 + X)/(14 + X)=65/100
Solving we get X = 6
So the minimum number of questions in the paper is
14 + X =14 + 6 =20
