Let's address the questions one by one:


  1. Mercy rounded off 499856 to the nearest ten thousands.


To round a number to the nearest ten thousands, look at the thousands digit:


  • The number is 499856.

  • The thousands digit is 9.

  • Since 9 is greater than or equal to 5, round up the ten thousands digit (which is 9) to 10 and change all trailing digits to zeros.


Therefore, 499856 rounded to the nearest ten thousands is 500,000.

Correct Answer: C. 500,000
