What is the estimate to nearest tens of the sum of greatest 3 digit even number and smallest two digit odd number?

A. 1250
B. 1110
C. 1010
D. 1000

Answer: C

Let’s find the greatest 3-digit even number first. The greatest 3-digit even number is 998.

Now, let’s find the smallest two-digit odd number. The smallest two-digit odd number is 11.

Next, let’s find the sum of these two numbers:

998 + 11 = 1009

Now, let’s estimate this sum to the nearest tens. The ones place digit is 9, which is greater than or equal to 5. Therefore, we round up the tens place to 1, and the ones place becomes 0. The estimated sum to the nearest tens is 1010.
