My father told me before he died,that he placed his gold coins in the box number 8 down in our basement, and he gave me its key .He said to me:

There are nine boxes in our basement,they were numbered from 1 to 9,,,,but I changed each number according to special procedure,inorder to prevent anybody to steal my money....and now I am going to tell you this procedure...it is as...foll...o..w...s...(and he didn`t say anything more...he died ).I went down to our basement,and I found nine boxes scattered here and there,on each box I found a number,I worte them down,,here are the numbers:

57,11,42,65,54,93,27,101,69

Now I have to use this key only once,,,but which box was number 8?

can you help me?

if yes...tell me which number originates from number 8....and...WHY?

Note: all the boxes have the same shape,weight(may be the others were filled with stones )

This seems better...

Panwar I think you are very close, I would modify your procedure slightly

Step 1 (same as pan war) take numbers 1 through 9 and multiply by 11 through 19 respectively

gives: 11, 24 39, 56, 75 96, 119, 144, 171

Step 2 take the right most two digits and reverse them to form another number

gives: 11, 42, 93, 65, 57, 69, 91, 44, 17

Step 3 take any (left most) digits not used in step 2, multiply them by 10 and add to the step 2 result

gives:

11 = (0*10) + 11

42 = (0*10) + 42

93 = (0*10) + 93

65 = (0*10) + 65

57 = (0*10) + 57

69 = (0*10) + 69

101 = (1*10) + 91

54 = (1*10) + 44

27 = (1*10) + 17

so I agree with panwar #54 is indeed box 8

you both reached the correct answer but with another way I did.

I did it like this:

1st step: take the numbers 1 to 9 and square them giving:

01,,04,,09,,16,,25,,36,,49,,64,,81

2nd step: reverse the numbers above giving:

10,,40,,90,,61,,52,,63,,94,,46,,18

3rd step: add the numbers from (1 to 9) to each number in step two respectively:

10+1= 11

40+2= 42

90+3= 93

61+4= 65

52+5= 57

63+6= 69

94+7=101

46+8= 54

18+9= 27

And so ,,,the box number 54 originates from number 8

Thank you all

I dont think most people would get a 2 digit answer for the squares of 1,2, and 3. I think most people would say the answers were 1,4, and 9 not 01,04,and 09. Just my 2 cents.

I also agree... I would take 2 square as 4 but not 04

I guess my solution is more clear...

instead of just finding the replacement for 8, i randomly tried fitting all the numbers with their corresponding 1-9 "partners".i worte the original no.s in a row:

1 2 3 4 5 6 7 8 9

and tried linking them with 42,57,11,65,54,93,27,101,69. this is stupid but i linked them based on which fake number contains a digit that is the same as the original number.

heres what i got:

1 - 11, 101(both no. have a 1)

2 - 27

3 - 93

4 - 42 (not 54 since it has to go with 5)

5 - 54 (not 65 since it has to go with 6, 57 goes with 7)

6 - 65(not 69 since it has to go with 9)

7 - 57(only no. that has a 7, except 27 that goes with 2)

which leaves 101 with 8.

i tried something completely illogical and random and one numberv popped out, magically. its probably not right but im not smart. i dont know what else to try.

other solution (off by 1 no.):

the code the dad left has 1,1,1,3,1,1,1 (syllabals) so if you replace them with no.s,you can kind of say 1+2+3(4)(5)(6)-7-8-9 = 102(closest no. in the list is 101, so just go with that i guess)

my answer is very simple , 69 lol put two digit together and it will look like 8
