i am unable to get the test cases,

k=number of people

n=the number of airplanes each should make,

s=the number of airplanes that can be made using one sheet,

p= the number of sheets in one pack,

so, we are given k =5, n= 3, s=2, p=3

so, 1 pack has 3 sheets, and one sheet can make 2 airplanes, so, 1 pack can make 6 airplanes, and we have 5 people and each has to make 3 airplanes, so total airplanes=15.

so, won;t it be 15/6=2.5=~3? we need 3 packs!! why 4?

can anyone please explain this.
