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**
