# Find the average price of a notebook.

20 pens and 35 notebooks were purchased for Rs. 1100. If the average price of the pens was Rs. 13, find the average price of a notebook.

- Rs. 32
- Rs. 28
- Rs. 35
- Rs. 24

**Answer: (4) Rs.24**

**Explanation:-**

The average price of a pen = Rs.13

Then, the total price of 20 pen = 13 x 20

= Rs.260

Then, the total price of notebooks = 1100 – 260

= Rs.840

Now, the average price of a notebook = 840/35

= Rs.24

Hence, the average price of notebook is Rs.24.
