45 of them.
There are 107 numerical palindromes between the numbers 1 and 1000, starting from 2 to 999.
There are 179 multiples of 5 between 101 and 999. 101 ÷ 5 = 201/5 → first multiple of 5 ≥ 101 is 21 x 5 999 ÷ 5 = 1994/5 → last multiple of 5 ≤ 999 is 199 x 5 → number of multiples of 5 between 101 and 999 is 199 - 21 + 1 = 179.
If by "between" you mean "between but not including", then the answer is 9999 - 999 - 1 = 8999.If on the other hand, you mean to include both 9999 and 999, then the answer is 9999 - 999 + 1 = 9001.
There are 280 of them.
