Explanation:
Since we have given that
Value of 2s in 55,220
As we have seen that there are two 2 s , one is in hundreds position and other is in tens .
Value of 2 which is in hundreds position = 200
Value of 2 which is in tens position = 20
On Comparing , we get the difference given by

Similarly,
There are two 5s , one is in thousands position and other is in thousands.
Value of 5 which is in thousands position = 50000
Value of 5 which is in hundreds position = 5000
On comparing , we get the difference is given by
