Solution
The correct option is A 27,133 Number of birds in the sanctuary = 33,289
Number of birds that migrated = 5,456
Number of birds left = Total number of birds – Number of birds that migrated
= 33,289 – 5,456
Let's subtract the numbers using vertical subtraction.
Vertical subtraction is a method of subtracting where the numbers are lined up in columns according to their place values.
Therefore, the total number of birds left is 27,133.
