A doctor in Michigan has a sister who lives in California but the sister does not have any brother that lives in Michigan, how come??
:P

Huuuhh just guessing 19 and 20.

No. The probability of getting the correct answer by random guessing is less than 0.0029. So, random guessing is as futile as anything.

(5 x 6 ) or (4 x 13 )

Answer Plz...................

meek_misfit....almost there!!. One of them is the answer while the other one isn't. Care to share how you came down to those two possible solutions?

By crossing Slacdemic and Meek misfit, the answer is 5 and 6, but how? I still did not get it. Are the once inch apart?

"By crossing Slacdemic and Meek misfit, the answer is 5 and 6, but how? I still did not get it. Are the once inch apart? "

I liked the way how you got to the answer. I did not realize that Slack had 4 x13 too. No, the dimensions do not necessarily have to be one inch apart. That is not given.

I will wait for meek or even slack to tell how they got what they got.

Ram has many combinations of l and b for his value of area. Shyam's value of perimeter cannot be the same value that can be derived from the value of area that Ram knows. Hence, by hit and error method, eliminate the combinations that matches l and b from Ram's area and Shyam's perimeter.

It can again be construed that by whatever Ram knows, two prime integers that produces the area value is not possible.
Alternatively, the value of l and b cannot be the product of two prime numbers in A= l x b.Otherwise, it would have been possible for Ram to know the value of (l+b) and decode the value of parimeter in 2(l+b).Again, Shyam also knows that the sum of two prime integers cannot be used to find (l+b) though he knows the value of parimeter as a whole. Had it been true, Shyam would have known that Ram knows (l+b).

The limitations are:
l>b>1
P<=80
(l+b)<=40

The least possible combinations can be that of 2 and 3. But that is not possible since those two are prime numbers again. Hence lets start from integer 4 ( which is not prime):

The values of (l+b) can be either 11, 17, 23, 27, 29 35 or37.

Iteratively, break all these numbers by hit and trial of (l+b) and (lxb). You will come to 5x6 as the obvious answer.Also, Area = 30 and Perimeter = 22.

Considering the letters below, they represent an addition problem. Different letters stand for different digits (chosen from among 0, 1, 2, ...,9). Two occurrrences of the same letter stand for the same digit.

Identify all the digits of this addition problem

L E T S
W A V E
----------
L A T E R

slackdemic,

L, A and E appears more tha 1 times, does all letters represend distinct numbers ???

Welcome to the show, Ritthe bro! How have you been?

Yes, if one letter appears more than one time, they all represent the same number.

heres is the answer
L= 1, E = 5, T= 6, S=7, W= 9, A=0, V=8, R=2

1567
9085
----------
10652

long time slackdemic, i havenot been in this thread for a while ........ feels like coming back home .... this thread rules ...... this seems though the question you have come up with ...... let me use my brains hehe

damn nepali thito so fast, i havenot even tried it ......... ;-))

Nepalithito, you got it! Congratulation!

Another one, but this IS multiplication:

. A T O M
. A T O M
------------------
. * * * * *
. * * * * *
. * * * * *
* * * * *
----------------
* * * * A T O M

Please disregard the "." sign that appears at the beginning of a few lines. Sajha doesn't let me indent so I used ".".

Oops, it again messed up. Just know that you are multiplying 4 numbers by same 4 numbers! And the last 4 digits of the answer you get will also have the same 4 numbers. Interesting, innit?

Ritthe, your turn now. Maybe you will have to hit f5 button to the brain several times! :P

Meek,
"Shyam's value of perimeter cannot be the same value that can be derived from the value of area that Ram knows."
Why not? I am not sure if I understood what you are saying either. Hit and error method is futile.

Your second paragraph is logically true, but I do not see its connection to the rest of your answer.

"The values of (l+b) can be either 11, 17, 23, 27, 29 35 or37."
Why only those values? Did I miss something? And, I find it mysterious that you got 5X6 as the obvious answer by hit and error method.

Anyway, good attempt though!

**The conversation between Ram and Shyam holds the key to the Pandora's box.

slackdemic, the answer is 9376.

Oh, I almost missed this thread. Ritthe, I am scratching my head looking at your answer. Can you give the details?

That is bit complicated, so even before it is solved, I have another interesting problem:

.* S E N D
* M O R E
---------------
M O N E Y

P.S. This is the additional problem.
