Say Team B distributes x boxes, each of which contains y booklets. Hence Team B distributes xy booklets.
Then Team A distributes 1.6x boxes (60% greater than x), each of which contains .4y booklets (60% less than y). Hence Team A distributes (1.6x)(.4y) booklets, or .64xy booklets.
Together, Team A and Team B distribute .64xy + xy booklets, or 1.64xy booklets. Now we have this equation:
1.64xy = (total # of booklets)
This means we need an answer choice that divides by 1.64 and leaves an integer, as xy must be a whole number. Manipulating our equation a bit, we get
164xy = 100 * (total # of booklets)
and since 164 = 4 * 41,
4xy = (100 * (total # of booklets))/41
So the total # of booklets must be divisible by 41. Only C is, so that's our answer!

Let the number of boxes = 10.
Let the booklets per box = 10.
Total booklets = 10*10 = 100.
Team A:
Since team A distributes 60% more boxes, the number of boxes = 1.6(10) = 16.
Since each box contains 60% fewer booklets, booklets per box = 10 - .6(10) = 4.
Total booklets = 16*4 = 64.
Total booklets for the two teams = 100+64 = 164.
The correct answer choice will be a multiple of 164 that ends in 0.
5*164 = 820.
5*820 = 4100.
The correct answer is C.

Hello,
I was trying to solve this problem as follows:
Boxes of booklets:
Team B distributes 100
Team A distributes 160
Booklets in each box:
Team B has x
Team A has 0.40x
Total Booklets distributed:
Team B is 100x
Team A is 160(0.40x)
So, 100x + 160(0.40x) = 164x
However, I am lost after this point. Can you please assist?
Thanks,
Sri

Well you are almost there.
Total number of books = 164x ie; 4*41*x. Look at the answer choices. There is only one answer choice which has 41 as a factor.
C
