Bet no one can figure this riddle out:?

Question

2 farmers meet at an intersection on a country road. both farmers have a truckload of pigs each. The first farmer says to the second, "If you give me one of your pigs, then I'll have twice as many pigs as you." The second farmer replies, "True, but if you give me one of your pigs, we'll both have the same amount." How many pigs did each farmer have?

Answer 1

Five and seven

By giving one, it's four and eight (twice)

By givng one, it's six and six

Answer 2

2 and 3

Answer 3

This is almost impossible, unless I have left something out. If we proceed as follows:

Let, X = number of pigs of first farmer and
Y = number of pigs of second farmer , before any exchange take place.

then we from their conversation, we can formulate the following equations;

X + 1 = 2(Y - 1) ------------------- (1)

Y + 1 = X - 1 -----------------------(2)

In equation (2), we can write it as,

Y = X - 2 --------------------------(3)

In equation (1), we can write it as,

X + 1 = 2Y - 2

X = 2Y - 3 -------------------(4)

In equation (4), in the place of Y put equation (3);

X = 2 ( X - 2) - 3
= 2X - 4 - 3
X - 2X = - 7

which gives X = 7 --------(5)

To obtain Y, in equation (3) put X = 7,

That is Y = X - 2 = 7 - 2 = 5

Thus X = 7 and Y = 5

From the above we observe that the first farmer had seven pigs and the second farmer had five pigs.

I doubt if there is any other possible solution. However, five and four seems to work just as well.

Good question by the way!!

Answer 4

Farmer #1 came in with a truckload of pigs, so did Farmer #2. If #1 gets one pig from #2 he'll have double as #2.

Equations

Let farmer #1 be a

Let farmer #2 be b
1...................b-1=a+1
2...................b-1=2(b)=a+1
3...................b+1=a-1

the only numbers fitting these circumstances were 5 and 7.

Thus, the answer is 5 and 7.

Answer 5

4 and 5

Answer 6

3. If a farmer with 3 pigs gave another farmer a pig, the other farmer would have 4 which is twice of 2.

Answer 7

5 and 7

Answer 8

I think that one farmer had 3 pigs and the other had 1.

Answer 9

one had 5 and the other 7

Answer 10

5 and 7.

Answer 11

3 & 2
