Sam divided a number of marbles into 5 equal groupd and found he had 1 left over. When he tried to divide them into group ,he had 2 left over.If Sam had more than 20 marbles, what was the least possible number of marbles that he had.
'When he tried to divide them into group' I think you left out some words in this part of the question....
0 So the answer has to be 21/26/31/36... etc.
If he had to then divide into groups of 4 he'd have left over: 1, 0, 3, 0...
If ditto 3, ditto: 0, 2... bang there it is - 26
If six, same as three... 26
If seven... nope
eight, same as four
So I worked it out even though the question was missing. Pretty Awesome, beat that Hawkings.
