(1) The tenths digit of 100m is 5.
(2) The tens digit of 1,000m is 5.
Statement 1: The tenths digit of 100m is 5.
Case 1: 100m = 0.5
Here, m = 0.005.
In this case, the hundredth digit of m is 0.
Case 2: 100m = 1.5
Here, m = 0.015.
In this case, the hundredth digit of m is 1.
Since the hundredth digit can be different values, INSUFFICIENT.
Statement 2: The tens digit of 1,000m is 5.
Case 3: 1000m = 50
Here, m = 0.05.
In this case, the hundredth digit of m is 5.
Case 4: 1000m = 152
Here, m = 0.152.
In this case, the hundredth digit of m is 5.
As Cases 3 and 4 illustrate, Statement 2 implies that the hundredth digit of m will always be 5.
SUFFICIENT.
The correct answer is
B.
