Bank reconciliation statement

Hello Supriya. First of all, you need to know either the balance as per Cash Book(Bank Column) or Pass Book in order to arrive at the other. 

Assuming that you know the Cash Book (Bank Column) Balance, this will be the solution :

Balance as per Cash Book XXX

ADD: Payments overcast 100

ADD : Cheques not encashed 1800

The sum of all these three will give you the Balance as per Pass Book. 
If you are having the Pass Book Balance and want to reach the Cash Book (Bank Column) balance, you are required to deduct these two items of adjustments from your Pass Book Balance.
