Empty the contents of the 3 litre can into the 5 litre can. - Leaving the 5 litre can full
and 1 Litre in the 3 litre can.
Empty the contents of the 5 litre can
Pour the 1 litre from the 3 litre can into the 5 litre can.
Fill the 3 litre can from the tap.
Pour contents of the 3 litre can into the 5 litre can.
therefor there will be 4 litres in the 5 litre can.

Farr out CAN you do that

So it is, I thought it had to be some form of sinusoidal expression because it went up and down, but dismissed it as it wasn't uniform, should have thought about tangential. Oh well, I like that question.

How is he able to choose the right door?

I think he could ask" is this the right way to heaven?"..

OK, if he ask that question to the guard that always tells the truth he should have the right answer and he decides the way....maybe????

A between 23 & 58, B between 146 and 366 and C between 366 & 916

Warnie

A=116, B=73, C=183

multiply 1st number by 5 and add 1, then halve, multipy 3rd number by 5 and add 1, then halve and have again, multipy the 6th number by 5 and add 1, then halve, multipy the 8th number by 5 and add 1, then halve, multipy the 10th number by 5 and add 1.

I think

Find A, B and C.

A = 23 x 5 + 1 = 116
B = 146/2 = 73
C = 366/2 = 183
