Two teams are distributing information booklets. Team A distributes 60% more boxes of booklets than Team B, but each box of Team A's has 60% fewer booklets than each box of Team B's. Which of the following could be the total number of booklets distributed by the two groups?

a)2,000
b)3,200
c)4,100
d)4,800
e)4,900

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!

Team B:
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

Hey 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.
