I owe house and receive rent from tenant. (All figures on yearly basis)
(A) Rent = 180000
(B) PMC Tax = 6500
(C) Society Maintenance = 18000
My question is : What will the INCOME FROM HOUSE PROPERTY?
Will it be
[A - 30%A - B - C]  = 180000 - (180000*30/100) - 6500 - 18000 = 101500
OR
[A - B - C - 30%(A-B-C)] = 180000 - 6500 - 18000 - ((180000-6500-18000)*30/100) = 108850

Is first option correct or second option correct or is there any other formula?
