The number of students in vans and bus are (8,22)
Step-by-step explanation:
Let the number of students in the van be “x”
Let the number of students in the bus be “y”
It is given that each bus and van have same number of students.
For college A-
8 vans and 8 bus were rented to ferry 240 students
No of students in 8 bus= 8y (since y students were in each bus)
No of students in 8 van= 8x (since x students were in each van)
Hence 8x+8y=240 cancelling the equation with common factor 8, the equation becomes ⇒ x+ y=30
For College B
4 vans and 1 bus were rented to ferry 54 students
No of students in 1 bus= 1y (since y students were in each bus)
No of students in 4 van= 4x (since x students were in each van)
4x+y=54
Comparing the both equation we get and subtracting equation 2 from 1
x+y-30-4x-y-54=0 ∵ Cancelling y
-3x=-24
∴ x=8 putting the value of x in equation 1 we get y as 22
Thus the answer is (8,22)
