Question

In a class, if three students sit on each bench, one student will be left. If four students sit on
each bench, one bench will be left. Find the number of students and the number of benches
in that class.
draw the graph and find the number of benches and students​

Answer 1

Answer:

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.
