Mike
has $20 more than Todd. How much does each have given that combined
they have $21 between them. You can’t use fractions in the answer.
(Hint: This is a trick question, pay close attention to the condition)
Mike has $20, Todd initially has $21. Todd keeps all
his money on the table between them. Hence, now Todd has nothing, Mike
has $20 more than Todd, and they have $21 between them i.e on the table
between them.
