Rajdeep Banerjee answered
Explanation:

To determine which option is the same as 8268 1232, we need to compare the two numbers and find the one that is equal to it.

Step 1: Compare the first number (8268) in each option with 8268

- Option a) 1232 8628: The first number is 1232, which is not equal to 8268.
- Option b) 5000 4500: The first number is 5000, which is not equal to 8268.
- Option c) 1232 8826: The first number is 1232, which is not equal to 8268.
- Option d) 1223 8268: The first number is 1223, which is not equal to 8268.

Step 2: Compare the second number (1232) in each option with 1232

- Option a) 1232 8628: The second number is 8628, which is not equal to 1232.
- Option b) 5000 4500: The second number is 4500, which is not equal to 1232.
- Option c) 1232 8826: The second number is 8826, which is not equal to 1232.
- Option d) 1223 8268: The second number is 8268, which is equal to 1232.

Conclusion:

From the comparison, we can see that option d) 1223 8268 is the same as 8268 1232. Therefore, the correct answer is option b) 5000 4500.

One hundred more than 546 is:
  • a)
    446
  • b)
    546
  • c)
    646
  • d)
    746
Correct answer is option 'C'. Can you explain this answer?

Rohit Sen answered
**Solution:**

To find out what one hundred more than 546 is, we need to add 100 to 546.

**Calculation:**

546 + 100 = 646

Therefore, one hundred more than 546 is 646.

**Explanation:**

When we add 100 to a number, we are increasing its value by 100. In this case, we are adding 100 to 546.

To add 100 to a number, we can start by adding the ones place. Since 6 plus 0 equals 6, we write down 6 in the ones place.

Next, we move to the tens place. Since 4 plus 0 equals 4, we write down 4 in the tens place.

Finally, we move to the hundreds place. Since there is nothing to add in this case, we simply write down the original digit, which is 5, in the hundreds place.

Therefore, the answer is 646.

**Conclusion:**

One hundred more than 546 is 646.

    3154
  • c)
    5044
  • d)

Anjali Gupta answered
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

    9443
  • c)
    8453
  • d)

Rhea Reddy answered

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

Pranav Singh answered
Nani gaves 2 of his markers to Raja.To find the solution, we need to make Raja and Nani have the same number of markers.

- Raja has 6 markers.
- Nani has 10 markers.

Let's analyze each option:

- Option A: If Raja gives 2 markers to Nani, Raja will have 4 markers and Nani will have 12 markers.
- Option B: If Raja gives 4 markers to Nani, Raja will have 2 markers and Nani will have 14 markers.
- Option C: If Nani gives 2 markers to Raja, Raja will have 8 markers and Nani will have 8 markers. This results in both having the same number of markers.
- Option D: If Nani gives 4 markers to Raja, Raja will have 10 markers and Nani will have 6 markers.

Thus, Option C (Nani gives 2 markers to Raja) is the correct action to make both have the same number of markers.

The next number in the series 105, 110, 115, 120, 125,..... is:
  • a)
    245
  • b)
    210
  • c)
    130
  • d)
    120
Correct answer is option 'C'. Can you explain this answer?

Sparsh Chavan answered
Next number in the series is obtained by adding 5 to the previous number.

Explanation:
The given series is 105, 110, 115, 120, 125,....

To find the pattern in the series, we can observe that each number in the series is obtained by adding 5 to the previous number.

105 + 5 = 110
110 + 5 = 115
115 + 5 = 120
120 + 5 = 125

Therefore, the next number in the series would be obtained by adding 5 to the last number, which is 125.

125 + 5 = 130

Hence, the next number in the series is 130.

Therefore, option c) 130 is the correct answer.

Which of the following numbers completes the addition sentence 789 + 253 = _______?
  • a)
    1032
  • b)
    1042
  • c)
    942
  • d)
    932
Correct answer is option 'B'. Can you explain this answer?

Pranav Singh answered

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
