Concept:Interest on drawings is computed as total drawings multiplied by the rate and the relevant time fraction.Explanation:Monthly drawings are NGN1,500.Total annual drawings =N1,500×12=N18,000.Drawings are assumed to be made evenly, so the average period is 6 months, i.e. 126 of the year.Interest is charged at 10% per annum.Thus, interest on drawings =N18,000×10010×126=N900.Answer:C. 900
