Correct Answer - Option 3 : Rs. 12,00,000
Given:
Salary spent on shopping, going to restaurants and malls = 15%
Remaining salary on household expenses = 40%
Salary goes to savings = 45%
Salary spent on the house = Rs. 40,000
Concept used:
1 year = 12 months
Calculation:
According to the question
⇒ 40% = 40,000
⇒ 100% = (40,000 × 100/40)
⇒ Rs. 100,000
Now,
Her annual income = Rs. (100,000 × 12)
⇒ Rs. 12,00,000
∴ The required annual income is Rs. 12,00,000
