Re: MATHS riddle
Here is the solution
Why it is impossible here it goes: as we said everyday we must kill a number impair(mefrid)of cows and we know enno impair+impair=pair for example(3+3=6 6=pair while 3=impair,7+7=14 etc....) so in every 2 days we have a number pair of cows that are going to die in 4 days we have also a number pair but in the 5th day we have an impair number while the number desired to be reached is 30 wich is pair cause 30 can be divided by 2 Cheers

Re: MATHS riddle
joe the sum of 5 odd numbers MUST be an odd number
(2n+1)*5 = 10n+5. knowing 10n is even(multiple of 2), and adding 5, we can tell that the result is odd. starting from the fact that 0 is not an odd number, you cannot have 5 odd numbers who sum up to 30. i dunno why u guys even tried finding the answer

Re: MATHS riddle
sorry i didn't reply sooner
my internet was down... but now it is working again duce and crystal soul got it right the answer is: 5 cigs how? well he has 10 10= 9+1 from the 9 he makes 3 cigs he smokes them and each cig produces a leftover now he has 3(from smoked cigs) and 1(from the original 10) so with the 3 he makes a cig and smokes it and so he get another leftover so now he has 2 he borrows 1 from his friend now he has 3 he makes them a cig and smoke it and get from it 1 leftover so he returns it to his friend
