1. **State the problem:** Noel is a farm worker paid 00 per kaing basket of mangoes harvested. He works 20 days a month and saves 30% of his monthly income (since he spends 70%). We need to find his monthly income and how much he saves. 2. **Define variables and formula:** Let the number of baskets harvested per day be $x$. Then monthly income $I = 00 \times x \times 20$. 3. **Given:** He spends 70% of his income, so savings $S = 30\%$ of $I$, or $S = 0.3I$. 4. **Calculate monthly income:** Since the problem does not specify $x$, assume he harvests 1 basket per day for calculation. $$I = 00 \times 1 \times 20 = 2000$$ 5. **Calculate savings:** $$S = 0.3 \times 2000 = 600$$ 6. **Answer:** Noel's monthly income is 2000 and he saves 600.
