• B. 4, 5, and 1
• C. 4, 6, and 1
• D. 4, 1, and 1

Answer 1

The correct option is B 4, 5, and 1

A few digits are missing in this addition.
While adding two numbers, the digits at ones, tens, hundreds, thousands, and ten thousands places of a number should be added to the corresponding digits at ones, tens, hundreds, thousands, and ten thousands places of another number.
To find the missing number, add the respective digits.
Add the digits at ones place: 5 + 9 = 14
- We have 14 ones. 14 ones as 1 tens and 4 ones.
So, the first missing number is 4.
- Add the digits at tens place = 1 + 7 + 5 = 13
- Regrouping of added tens (13 tens): 1 hundreds and 3 tens
- Addition of digits at hundreds place = 1 + 8 = 9. If we add 5 with, 9 + 5 = 14.
So, the second missing number is 5.
- Regrouping of added hundreds (14 hundreds): 1 thousands and 4 hundreds
- Add the digits at thousands places = 1 + 3 + 1 = 5
- The addition at the ten thousands place should come 0. So, if we add 1 to 9, it gives 10. Regrouping of added ten thousands (10 thousands): 1 hundred thousands and 0 thousands.
So, the third missing number is 1.

The addition of digits at hundred thousands place = 1 + 3 = 4
Hence, the missing digits from right to left are 4, 5, and 1.
