If you count in pairs, one remain
If you count in threes, two remain
If you count in fours, three remain
If you count in fives, four remain
If you count in sixes, five remain
If you count in sevens, no chocolate remain.

Can you analyze the statements and tell us how many chocolates were lost?

Answer 1

31 chocolates missing
since 119 chocolates were present
If you count in pairs = 118, one remain = 1
If you count in threes = 117, two remain = 2
If you count in fours = 116, three remain = 3
If you count in fives = 115, four remain = 4
If you count in sixes = 114, five remain = 5
If you count in sevens = 119, no chocolate remain
