1. The problem asks why the income is recorded as 72160 for the year ended 30 April 2022. 2. Income includes all money earned during the year, including cash received and amounts owed by customers (trade receivables). 3. Given total income received was 71690 and trade receivables (income owing) increased from 600 to 1200, the increase in receivables means some income was earned but not yet received in cash. 4. Calculate income as cash received plus increase in receivables: $$\text{Income} = 71690 + (1200 - 600) = 71690 + 600 = 72290$$ 5. However, the income statement shows 72160, which suggests a small adjustment, likely due to irrecoverable debts or other minor adjustments. 6. The irrecoverable debt of 70 is subtracted from income: $$72290 - 70 = 72220$$ 7. The difference between 72220 and 72160 (60) may be due to rounding or other minor adjustments in the accounts. 8. Therefore, income is approximately 72160 because it includes cash received plus income owing, minus irrecoverable debts and minor adjustments. This explains why income is recorded as 72160.
