What is the hundreths digit of the decimal m?
(1) The tenths digit of 100m is 5.
(2) The tens digit of 1,000m is 5.
The thing that confuses me is what do they mean by decimal m and then how that apply in 100m and 1000m. Can someone please explain?

What is the hundredths digit of the decimal m?
Let's say \(m=a.bcd\). The hundredths digit of z would be the value of \(c\). So the question is \(c=?\)
(1) The tenths digit is 100m is 5 --> \(100m=100*a.bcd=abc.d\) --> the tenths digit of \(100m\) is the value of \(d\). So \(d=5\). We need \(c\). Not sufficient.
(2) The tens digit of 1,000m is 5 --> \(1000m=1000*a.bcd=abcd\) --> the tens digit of \(1000m\) is the value of \(c\). So \(c=5\). Sufficient.

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