    Step-by-step explanation:

    Cost of 14 copies is Rs 240

    Cost of 1 copy =Rs 240/14 = Rs 120/7 =Rs 17.14

    CP = Rs 17.14

    Cost of 10 copies is Rs 160

    Cost of 1 copy = Rs 160/10 = Rs 16

    SP = Rs 16

    Loss = CP – SP

    = Rs (17.14-16)

    = Rs 1.14

    Therefore, loss percentage = (Loss/CP × 100)%

    = (1.14/17.14×100)%

    = (114/1714×100)%

    = 6.65%

    Answer:

    =cp of 14 copy is 240

    =cp of 1 copy is 240÷14

    =17.1428571

    =sp of 10 copy is 160

    = sp of 1 copy is 160÷10

    =16

    therefore he loss = 17.1428571 -16

    =1.1428571

    loss %= 100+loss ÷ 100 × cpt

    = 100+1.1428571 ÷100x
