Correct Answer: INR 139
Solution : The number of chairs of cost INR 150 bought = 13 The number of chairs of cost INR 130 bought = 15 Now, the Average price of a chair = $\frac{\text{Total price of all chairs}}{\text{Total number of chairs}}$ = $\frac{13 × 150+ 15×130}{13+15}$ = $\frac{3900}{28}$ = $139.28\approx 139$ Hence, the correct answer is INR 139.
