Thanks very much Bunuel. I take it you mean m and not Z in your explanation above.

Digits before decimal point doesn't matter for this problem. You can pick 0.abcd, 0.abc, 123.abc, ... it won't change the answer. We are just interested in hundredths digit of the decimal m, so when expressing it somehow make sure that you know which value are you looking for. For example for 123.abc it would be the value of b, you can substitute it in both statements to see that the answer will be exactly the same:

(1) The tenths digit is 100m is 5 --> 100m=123ab.c --> can not get b.
(2) The tens digit of 1,000m is 5 --> 1,000m=123abc --> b=5.

Hope it's clear.
