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 = 48You need to login to perform this action.
