For example:
- For the number 394, the sum of the first and second digits is 3+9=12
- For the number 632, the sum is 6+3=9
- For the number 783, the sum is 7+8=15
- For the number 576, the sum is 5+7=12
- For the number 895, the sum is 8+9=17
Now let's check each sum for divisibility by 3. A number is divisible by 3 if the sum of its digits is divisible by 3.
- 1212 (from 394) is divisible by 3.
- 99 (from 632) is divisible by 3.
- 1515 (from 783) is divisible by 3.
- 1212 (from 576) is divisible by 3.
- 1717 (from 895) is not divisible by 3.
Thus, the sum of the first and second digits of the number 895 is not exactly divisible by 3. The correct answer is: 895

Analysis:
To solve this question, we need to find the sum of first and second digits of each number given and check which number’s sum is not divisible by 3.
Calculation:
- For number 394, sum of first and second digit = 3 + 9 = 12
- For number 632, sum of first and second digit = 6 + 3 = 9
- For number 783, sum of first and second digit = 7 + 8 = 15
- For number 576, sum of first and second digit = 5 + 7 = 12
- For number 895, sum of first and second digit = 8 + 9 = 17
Out of these numbers, the sum of first and second digits of number 895 is 17, which is not divisible by 3. Hence, the correct answer is option A, i.e., 895.
Conclusion:
The sum of first and second digits of each number can be easily calculated by adding the first and second digit of the given number. In this way, we can determine which number’s sum is not divisible by 3.
