Answer:
possible number of students can be 2 , 4 or 5
Explanation:
Given:
Total number of cookies = 20
Total number of pizza slices = 40
Now,
The ration of Pizza to Cookies =
= 2:1
therefore,
For every 1 cookie a student can have 2 pizzas
Now,
let the number of students be x and y be the number of cookies each student had
therefore,
x × y = 20
here,
we can have
x = 1 and y = 20
x = 2 and y = 10
x = 4 and, y = 5
x = 5 and y = 4
hence,
the possible number of students can be 2 , 4 or 5
