| Answer:7. |
| By observation we can say A=5. So units places sum is 6. Now we need to find the values of B and C. |
| If we think B is 0 then C should be 9 and it will make hundreds place invalid. |
| As we are adding B to 9, it will be obviously have a carry. So it indicates C is 6. |
| Now by back tracking, to get 6 in hundreds place, B should be 7. |
