Correct Answer - Option 4 : Rs. 40500

**Given:**

Salary ratio = 16 : 11

A's expenditure = 4/3 of B's expenditure

A's savings = 6000 + B's savings

A's savings = Rs. 12000

**Calculation:**

Let expenditure of B be Rs. x

A's expenditure = 4x/3

B's savings = 12000 - 6000 = 6000

A.T.Q

(4x/3 + 12000)/(x + 6000) = 16/11

⇒ 44x/3 + 132000 = 16x + 96000

⇒ 4x/3 = 36000

⇒ x = Rs. 27000

B's salary = 27000 + 6000 = 33000

A's salary = 4/3 × 27000 + 12000 = Rs. 48000

Average salary = (33000 + 48000)/2 = Rs. 40500

**∴ The average salary is Rs. 40500**
