Correct Answer - Option 1 : 80

**Given:**

Increment of the salary = 15%

Salary after increment = Rs. 92

**Calculation:**

Let the basic salary = Rs. y

Then,

Salary after increment = y + 15% of y = Rs. 92

⇒ 115y/100 = 92

⇒ y = (92 × 100)/115 = 80

⇒ y = Rs.80

**∴ The basic salary is Rs. 80**
