A. multiplication is your answer.
Answer:
64
Step-by-step explanation:
16/100 = x / 400
Cross multiply:-
100x = 16*400
x = 6400 / 100
= 64

Let the capacity of bus be x students
And van be y students, now ;
From the given statements we get two equations ~


multiply the equation (2) with 2 [ it won't change the values ]


Now, deduct equation (1) from equation (3)




Therefore each bus can carry (x) = 45 students
Now, plug the value of x in equation (1) to find y ~







Hence, each van can carry (y) = 17 students in total.
