18 the 1 is smaller than the 8 in the ones place.
86 the 6 is 3x2
120 it could not be this number for it has three digits.
42 the 2x2=4 therefore it couldn’t be 42.
46 the 4 is smaller than the 6 in the ones place.
64 IS THE ANSWER
80 8+0= 8 which isn’t a multiple of 5 times
8 it could not be this for it has one digit.
22 2+2+ 4 which isn’t a multiple of 5
83 3 isn’t even.

The number has two digits
Both digits are even
The digit in the tens place is greater than the ones place
The digit in the ones place is not in the three times table
The tens digit is not double the ones digit
The sum of the two digits is a multiple of five
