    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.
