    Answer: (4) 80

    Explanation:-
    Let the number of  stamps be X which cost  of a stamp  is 60 p  & the number of stamps Y which cost of a stamp is 35 p.
    The total number of stamp = 167
    Then, X + Y = 167          …………………….. (1)
    The total cost of stamps = Rs.68.20
    Then, 60 X + 35 Y = 167
    Divide by 5 ,
    12 X + 7 Y  = 13.64                      …………….. (2)

    Solve equation (1) & (2) ,
    X = 67 & Y = 80

    Then, the number of 35-paisa stamps is 80.

    Hence, the answer is (4) 80.
