    Let the number of students in the class be x and number of benches in the class be y.

    According to the question,

    3y+1=x

    x−3y=1 …… (1)

    Also,

    (y−1)4=x

    4y−4=x

    x−4y=−4 …… (2)

    Solving equations (1) and (2), we get

    x=16 and y=5

    Hence, the number of students in the class is 16 and the number of benches in the class is 5.
