Chetan spends 60% of his income. If he saves ₹66,000, then his income (in ₹) is:

When a person spends a certain percentage of their income, the remaining percentage of that income is what they save: Savings = (100 − Expenditure %) of Income. So, given the savings amount, the income can be found as Income = Savings ÷ (Savings percentage ÷ 100).

1. Chetan spends 60% of his income, so he saves 100% − 60% = 40% of his income.

2. Let his income be ₹x. Then his savings = 40% of x = 0.40x.

3. The savings are given as ₹66,000, so 0.40x = 66,000.

4. Solving for x: x = 66,000 ÷ 0.40 = ₹1,65,000.

Check: 60% of ₹1,65,000 = ₹99,000 is the amount spent, and the remaining ₹1,65,000 − ₹99,000 = ₹66,000 matches the given savings, confirming the value.

So, Chetan's income is ₹1,65,000.
