Test: Addition of 3 Digit Numbers - Class 1 MCQ

• To find the sum of 27 and 35, start by writing the numbers down: 27 and 35.
• Add the ones place: 7 (from 27) + 5 (from 35) = 12. Write down 2 and carry over 1.
• Now add the tens place along with the carry: 2 (from 27) + 3 (from 35) + 1 (carry) = 6.
• Combine the results: The final sum is 62.

• Start by adding the hundreds: 100 + 200 = 300.
• Next, add the tens: 50 + 30 = 80.
• Then, add the units: 4 + 8 = 12.
• Finally, sum them all: 300 + 80 + 12 = 392.
• Thus, the correct answer is 392.

To find the sum, add the two numbers together: 546 + 183 = 729.

• To solve 89 + 245, start by aligning the numbers by their place values:
• 89
  + 245
  ------
  
• Add the digits from right to left:
• 9 (ones) + 5 (ones) = 14 → write 4 and carry over 1.
• 8 (tens) + 4 (tens) + 1 (carried over) = 13 → write 3 and carry over 1.
• 2 (hundreds) + 0 (from 89) + 1 (carried over) = 3.
• So, the total is 334.
