"A palidromic number is a number that reads the same when the order of its digits is reversed. What is the difference bettween the largest and smallest five digit number that are both multiples of 45." I got this question in an hour and a half test for year 7's?!
+6251 are you allowing leading 0's or not?
If not then in order for one of these numbers to be divisible by 45 it must end, and thus start, with 5.
I show the largest is 59895, and the smallest is 50805, and the difference is 9090.
If you are including numbers such as 01510, the answer will be different.
