Test: Addition- 1 - Class 3 MCQ

When we add 1 to a number, we get the successor of that number.
Hence, 1200 + 1 = 1201

Add the ones column as 0 + 0 + 0 = 0
Add the tens column as 7 + 6 + 2 = 15
Regroup 15 tens as 1 hundred and 5 tens.
Carry over 1 hundred to the hundreds column. Write 5 in the tens column.
Add the hundreds column as 1 + 5 + 4 +1 (carry over) = 11 Regroup 11 hundreds as 1 thousand + 1 hundred.
Carry over 1 to the thousands column.
Add the thousands. 1 + 2 + 1 (carry over) = 4
Hence, 2170 + 560 + 1420 = 4150 

When we add 8268 + 1232, we get 9500. When we add 5000 + 4500, we get 9500.


Hence, 8268 + 1232 is the same as 5000 + 4500.

Add the ones. 9 + 3 = 12 ones. Regroup 12 ones as 1 ten + 2 ones.
Write 2 in the ones column and carry over 1 to the tens column.
Add the tens. 8 + 5 + 1 (carry over)= 14 tens.
Regroup 14 tens as 1 hundred + 4 tens.
Write 4 in the tens column and carry over 1 to the hundreds column.
Add the hundreds. 7 + 2 + 1 (carry over)= 10. Regroup 10 hundreds as 1 thousand + 0 hundreds.
Write 0 in the hundreds column and carry over 1 to the thousands column.
Add the thousands. 1 + 0 + 0 = 1. Write 1 in the thousands column.
Therefore, 789 + 253 = 1042

Add the ones column as 4 + 9 = 13 Write 3 in the ones column.
Carry over 1 to the tens column.
Add the tens column as 5 + 9 + 1 (carry over) = 15 Write 5 in the tens column.
Carry over 1 hundred to the hundreds column. Add the hundreds column as 9 + 4 + 1 (carry over) = 14 Write 4 in the hundreds column.
Carry over 1 thousand to the thousands column.
Add the thousands. 6 + 2 + 1 (carry over) = 9.
Write 9 in the thousands column.
So, 6954 + 2499 = 9453

700 + 130

• The series given is 105, 110, 115, 120, 125.
• Observe the pattern: each number increases by 5.
• Starting from 105:
  
  • 105 + 5 = 110
  • 110 + 5 = 115
  • 115 + 5 = 120
  • 120 + 5 = 125
  
  
• To find the next number: 125 + 5 = 130.
• Thus, the correct answer is 130.
