Jeff has two brothers and each of his brothers has three sisters and each of
the sisters has four step brothers.  How many step brothers does each brother
have?

<think> Okay, so I've got this problem: Jeff has two brothers, and each of his
brothers has three sisters. Then it says that each of the sisters has four step
brothers. The question is asking how many step brothers each brother has.

Hmm, let me start by breaking down the information piece by piece. First, Jeff
is one person, right? And he's got two brothers. So in total, there are three
brothers: Jeff and his two brothers. Wait, no, wait—actually, when it says
"Jeff has two brothers," that means including Jeff or excluding him? I think in
most cases, when someone says they have a certain number of brothers, it
doesn't include themselves. So if Jeff has two brothers, then there are three
boys in total: Jeff plus his two brothers.

Now, each of these brothers (including Jeff?) has three sisters. Wait, no—that
part might be about the brothers excluding Jeff? Because it says "each of his
brothers," so that would mean Jeff's two brothers each have three sisters. So
does that include or exclude Jeff? I think in this context, when talking about
siblings, it usually refers to different people.

So if Jeff has two brothers and those two brothers have three sisters each,
that means there are three sisters in the family because they share the same
sisters. So three girls: let's say Anna, Bella, and Claire. Each of Jeff's
brothers (Brother 1 and Brother 2) have these three sisters.

Now, the next part says each sister has four step brothers. Step brothers would
be brothers from a stepparent relationship—so either through marriage or
another family situation. So each sister has four step brothers. The question
is: how many step brothers does each brother (Jeff and his two brothers) have?

Wait, so do the sisters' step brothers include Jeff's existing brothers? Or are
they separate? Let me think.

If each sister has four step brothers, that could be in addition to their
biological brothers. But then, since there are three sisters, who all share the
same step brothers, those four step brothers must be shared among them. So the
total number of step brothers for each sister is four, but Jeff's existing
brothers might or might not be part of this.

But wait, the question is about how many step brothers each brother (Jeff and
his two brothers) have. That means we need to figure out from their perspective
how many step brothers they have.

So if each sister has four step brothers, those are the same for all sisters
because siblings share the same step brothers. So the four step brothers are
additional to Jeff and his two brothers? Or do they include them?

Wait, that's a key point. If the sisters' step brothers are in addition to
their biological brothers (Jeff and his two brothers), then each sister has 4 +
3 = 7 brothers total, but I don't think that makes sense because the question
says each sister has four step brothers. So perhaps those step brothers are
separate from their biological brothers.

So let me clarify: There are three sisters. Each of these sisters has four step
brothers. Are these step brothers in addition to Jeff and his two brothers? Or
does "step brother" refer to any male siblings, including the biological ones?

Wait, no—usually, a step brother is someone who isn't biologically your sibling
but is related through marriage. So if the sisters have four step brothers,
they don’t include their own biological brothers (Jeff and his two brothers)
because those are already established.

So in that case, each sister has four step brothers outside of Jeff and his two
brothers. That would mean there are four additional male siblings from a
different family union—maybe through a parent's remarriage or something like
that.

But wait, the question is about how many step brothers each brother (Jeff and
his two) have. So for Jeff, his brothers are his brothers, but do they also
have step brothers? Or does it mean all of their male siblings that aren't
biological?

Wait, maybe I should approach this differently. Let's consider the family
structure:

- Number of brothers: 3 (Jeff plus his two brothers)
- Number of sisters: 3
- Each sister has four step brothers.

So each sister has four step brothers, meaning in addition to Jeff and his two
brothers? Or including them?

Wait, no—if a sister has four step brothers, that could mean they are separate
from her biological brothers. So for the sisters, their total number of male
siblings would be 4 (step) + 3 (biological) = 7. But that might not necessarily
be how it works because step siblings aren't counted as your own siblings.
Wait, no—step siblings are still considered siblings in a family sense.

But perhaps I'm overcomplicating this. Let me try to model the family:

Biological Family:
- Boys: Jeff and his two brothers (3)
- Girls: Three sisters (Anna, Bella, Claire)

Let's say one of the parents remarries someone with four sons. Then those four
sons become step brothers to the existing children.

So from Jeff's perspective, he has his two brothers (biological) plus four step
brothers from the stepparent's side. Similarly, each brother would have their
own biological brothers and the four step brothers.

But wait, the question says that each sister has four step brothers. So perhaps
when a parent remarries, they bring in four sons, making those the step
brothers for all the children—Jeff, his two brothers, and the three sisters.

So each child (Jeff, Brother 1, Brother 2, Anna, Bella, Claire) would have four
step brothers from the stepparent's side. That means Jeff's own brothers are
still his biological brothers, but they also acquire four step brothers each.

But wait, does that mean each brother now has four step brothers in addition to
their two brothers? So for example, each brother would have 2 bio brothers and
4 step brothers, making a total of six male siblings. But the question isn't
about total; it's specifically about step brothers.

Wait, let me read the problem again: "Jeff has two brothers and each of his
brothers has three sisters and each of the sisters has four step brothers." How
many step brothers does each brother have?

So perhaps when it says each sister has four step brothers, that refers to from
their perspective. But for the brothers, the number of step brothers would be
the same as what the sisters have.

Wait, no—each sister's step brothers are the same set of boys because they're
all in the same family. So if Anna has four step brothers, then those same four
are step brothers to Bella and Claire as well. Similarly, those four would also
be step brothers to Jeff and his two brothers.

So from Jeff's perspective, he already has two biological brothers. Now,
through a stepparent, they gain four more brothers—so each brother (Jeff
included) now has four step brothers in addition to their existing brothers.

But wait, the question is about how many step brothers each brother has, not
total brothers. So the answer would be four. But let me make sure I'm not
missing anything.

Alternatively, perhaps the four step brothers include Jeff's two biological
brothers. That doesn't seem right because they're already part of the family
before any remarriage happens. So if a parent marries someone with four sons,
those are additional to the existing three boys.

Therefore, each sister would have four step brothers (the four new ones), and
each brother would also have four step brothers (those same four). So the
answer is four.

Wait, but let me confirm:

Total biological brothers: 3 (Jeff + two) Each sister has four step brothers,
so these are separate. Therefore, each brother now has those four as step
brothers. So each brother has four step brothers. </think>



The problem involves determining how many step brothers each of Jeff's brothers
has. Here's the breakdown:

1. **Biological Brothers and Sisters**:
   - Jeff has 2 brothers, making a total of 3 biological brothers (including
     Jeff).
   - These three brothers have 3 sisters.

2. **Step Brothers Perspective**:
   - Each sister has 4 step brothers. Since the step brothers are shared among
     all siblings, each brother (Jeff and his two brothers) also has these same
     4 step brothers.

Therefore, each brother (Jeff included) has 4 step brothers in addition to
their biological siblings.
