good one man, i just needed to organize the equation in my head a little bit ...

I'll post a one but it's very difficult ... and the solution isn't in my head right now ...
you have 12 balls same size and shape, one of them has different weight (more or less) ... you have a scale, and you are only allowed to use it 3 times ... figure out the abnormal ball and if it's more or less than the other 11 ones ... remember you have to cover all possible probability with 3 scales only
Hint : enumerate the balls from 1 to 12 to make it easy 4 you
P.S: for this riddle don't PM me ... directly post your answer here

in the meanwhile if any has other riddles ... post it plz


Thank You ...

Abousoun's One:

First Of All, If The Ball Is Less Weight:
We Put 1,2,3 And 4,5,6 On The Scale. // We Used 1 Time The Scale So Far.
If(They're Equal Weight)
{
// The Ball Is Definitely Between The 7,8,9,10,11 And 12.
We Put 7,8,9 And 10,11,12 On The Scale. // 2 Times The Scale.
If(7,8,9 Weights Less Than 10,11,12)
{
// The Ball Is Between 7,8,9.
We Put 7 And 8 On The Scale. // 3 Times The Scale.
If(They Weight The Same)
The Ball 9 Is The One We're Looking For
Else
The Ball That Weights Less Is The One We're Looking For.
}
Else
{
// The Ball Is Between 10,11,12.
We Put 10 And 11 On The Scale. // 3 Times The Scale.
If(They Weight The Same)
The Ball 12 Is The One We're Looking For
Else
The Ball That Weights Less Is The One We're Looking For.
}
}
Else
{
// The Ball Is Definitely Between The 1,2,3,4,5 And 6.
We Put 1,2,3 And 4,5,6 On The Scale. // 2 Times The Scale.
If(1,2,3 Weights Less Than 4,5,6)
{
// The Ball Is Between 1,2,3.
We Put 1 And 2 On The Scale. // 3 Times The Scale.
If(They Weight The Same)
The Ball 3 Is The One We're Looking For
Else
The Ball That Weights Less Is The One We're Looking For.
}
Else
{
// The Ball Is Between 4,5,6.
We Put 4 And 5 On The Scale. // 3 Times The Scale.
If(They Weight The Same)
The Ball 6 Is The One We're Looking For
Else
The Ball That Weights Less Is The One We're Looking For.
}
}

LOOOL! I Turned It Into A C++ Porgram!
Anyways, If The Ball Weights More, Same Steps, But ... You Know What lol

Your thinking is mazbout 100 % and logical only if we consider that the abnormal ball is less or more in weight from the beggining ... you can't take the probability of it's less first and then the probability it's more a second time ... coz you'll be consumming the scale more than 3 times

Though i liked your response and the way of presentation

Thank You ...

Ok.This is hard and it's Pure maths

A man lost his security code for his pc !! and this code is composed using 5 digits

the 1st number + the fith number=14

the 4th number is bigger then the 2nd number bi 1 number(el ra2em el rabi3 akbar men el ra2em el tene bi ra2em wa7ad)

The 1st number is less than the double of the 2nd bi 1 number(el ra2em el awal 2a2al men do3ef el ra2em el tene bi ra2em wa7ad)

the 2nd # +The 3rd#=10

The addition of all numbers makes=30

what is the code??
