Accounts NPO

education institution has three branches

branch 1
fy 17 -18 receipt payment statement shows 1000 op bank bal, 2000 closing balance

branch 1
in fy 18 -19 receipt and payment statement shows 2000 op bank bal,
2000 closing bal

here management says that till fy 17-18 branch 1 used bank account
after this period branch 3 used the that bank account
and at end of fy 17-18 it has closing balance of 2000

so in fy 18 -19 we put op bank balance 2000 and closing balance also 2000
is it correct???
