Madhu's income is RS 12000 per month . She pays 20% tax on monthly income above Rs 2000 and she spends 30% of the remaining income. How much does she save annually

Answer 1

20% of (12000-2000) = 2000
30% of the remaining 10000 is 3000

so now you can see how much she saves monthly, and thus can figure the annual savings.
