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.
