    There are some benches in a classroom. If 4 students sit 01 each bench, then 3 benches are left unoccupied. However, 3 students sit on each bench, 3 students are left standing. How many students are there in the class?

    A)  36                               

    B)  48

    C)  56                               

    D)  64

    Correct Answer: B

    Solution :

    Let there be x students in the class. When 4 students sit on each bench, number of benches             \[=\left( \frac{x}{3}+3 \right)\] When 3 students sit on each bench, number of benches                         \[=\left( \frac{x-3}{3} \right)\]             \[\therefore \] \[\frac{x}{4}+3=\frac{(x-3)}{3}\] \[\Leftrightarrow \] \[3x+36=4x-12\,\,\,\,\Leftrightarrow \] Hence, number of student in the class = 48
