The average expenditure of Raman for 5 days is Rs.130. If his expenditure for the first 4 days is Rs.100, Rs.125, Rs.85 and Rs.160 respectively, then what is his expenditure (in Rs) of the $$5^{th}$$ day?
Average expenditure of Raman in 5 days = Rs. 130
=> Total expenditure in 5 days = $$5\times130=Rs.$$ $$650$$
Expenditure of first 4 days = $$100+125+85+160=Rs.$$ $$470$$
=> Expenditure of 5th day = $$650-470=Rs.$$ $$180$$
=> Ans - (B)
