Question 334546
The number either begins with {{{7}}} or {{{8}}}
If the tens digit is {{{7}}}, the units digit is {{{4}}} or less
If the tens digit is {{{8}}}, the units digit is {{{3}}} or less
and
If the product of the digits, the tens digit can't be {{{8}}},
since {{{8*3 = 24}}} is the most the product can be
and
George's number must be {{{74}}}, since {{{7*4 = 28}}}
which is OK, and {{{7*3 = 21}}} which fails the 2nd test
