Concept:For a business that pays rent for a whole year, only the rent relating to the month under review is charged as an expense. The rest is treated as prepaid rent in the balance sheet.Explanation:Rent paid for 12 months is ₦12,000.Rent expense for one month is ₦12,000×121=₦1,000.Prepaid rent at the end of the month is ₦12,000−₦1,000=₦11,000.Cost of sales is ₦15,000−₦10,000=₦5,000.Gross profit is ₦8,200−₦5,000=₦3,200.Total expenses are ₦500+₦1,000=₦1,500.Net profit is ₦3,200−₦1,500=₦1,700.Non-current assets are ₦10,000+₦1,500=₦11,500.Current assets are ₦9,200+₦10,000+₦11,000=₦30,200.Total assets are ₦11,500+₦30,200=₦41,700.This equals capital plus net profit: ₦40,000+₦1,700=₦41,700.
