I thinkgmatophobia , you have unnecessarily made the solution bigger . From the matrix , it is obvious that the minimum value of non fiction books is 20 . It can be >= 20 , depending on the value of paper back and non fiction books.
hence the minimum no of total books = 40 + 20 = 60. It is actually >= 60.KarishmaB
The information from the question can be plotted into a 2*2 matrix as shown below. As N represents the number ofbooks
\( N-60 \geq0\)
\( N \geq60\)
Least possible value of N =60
OptionB
