A school organises a fundraising event. The student commitee sells 47 entry tickets at \(₹80\) each and spends \(₹1200\) on arrangements. During the event, 19 additional tickets are sold at the same price, but the school provides a discount of \(₹15\) on each of these tickets. Later, the committee receives a donation of \(₹750\) and pays \(₹300\) for cleaning. The students represent income as positive integers and expenses as negative integers.
(i) Which expression correctly represents the total remaining amount?
(ii) What is the total income from ticket sales alone?
\(₹\)
(iii) If the cleaning expense increases by \(₹150\), what is the revised amount remaining?
\(₹\)
