Given: m = 0.008163

The digit 1 is in ten thousandth place of 0.008163
Since next digit (in the hundred thousandth position) is greater than 4, we must ROUND UP

So, when we round 0.008163 to the nearest to ten thousandth, we get: 0.0082
In other words, M = 0.0082

So, M + m = 0.0082 + 0.008163
= 0.016363

Answer: C

0.008163 rounded to the nearest ten thousandth is 0.0082.

So M + m is 0.0082 + 0.008163 = 0.016363.
