Hey Guys,
Here is the practice question I came across in the Kaplan Math workbook:
A class of 40 students is to be divided into smaller groups. If each group is to contain 3,4,or 5 people, what is the largest number of groups possible?
So I minimized the big groups to 1 each, and maxed the number of 3's groups but since there was a remainder, created 1 more group of 4, so 9 groups of 3. 2 groups of 4, 1 group of 5.
The OG however, says "each group must have at least 3 people in it" so create as many groups of 3 as possible. But that's NOT what the question says! The question says each group IS TO (i.e. must) contain 3,4 or 5 people.
Anyone else have the same line of thinking as me? Or should I be assuming even if it says "is to" that actually means "can but doesn't have to be"?
