JavaScript Volunteers Team question

Question

Hello everyone, here is the question (which I think should be worked out without “else if” as Sololearn has not taught us at this part yet)

Answer 1

But you can use ternary operator instead :)
Did you try?

Answer 2

Volunteers have been divided into 5 groups with equal number of members. If any group has fewer than 5 people, more volunteers must be recruited to fill the empty spots.
Write a program that takes the number of volunteers and outputs to the console how many volunteers need to be hired to have 5 equal groups.

Sample Input
24

Sample Output
1

Explanation
The nearest number to 24 that is multiple of 5 is 25, so we need 1 more volunteer (24+1=25) to get 5 equal groups.
