Answer :
To solve the given question, we need to calculate the sum of 65 and 84. Let's go through the steps together:
1. Set up the problem: We have the numbers 65 and 84, and we need to find their sum.
2. Align the numbers for addition:
```
65
+ 84
```
3. Add the units place: The numbers in the units place are 5 and 4.
[tex]\[ 5 + 4 = 9 \][/tex]
So, we write down 9 in the units place of the result.
4. Add the tens place: The numbers in the tens place are 6 and 8.
[tex]\[ 6 + 8 = 14 \][/tex]
We need to carry over 1 to the hundreds place and write down 4 in the tens place of the result.
5. Combine the results: When we combine our results, we have:
[tex]\[ 149 \][/tex]
Therefore, the sum of 65 and 84 is 149.
Let's verify this with the options provided:
- 194: This is not the correct answer since we determined the sum to be 149.
- 149: This matches our calculated sum.
- 21: This is not the correct answer since the sum we calculated is 149.
Thus, the correct answer is:
[tex]\[ \boxed{149} \][/tex]
