    Answer:

    let sp of a pen be x

    loss=20%

    then CP = ( SP * 100 ) / ( 100 – percentage loss )

    = x*100/80

    =1.25x

    Again

    if sp= x=10

    then profit =5%

    CP = ( SP * 100 ) / ( 100 + percentage profit )

    = (x+10)*100/105

    = 20x+200/21

    as cp is equal

    1.25x= (20x+200)/21

    26.25=20x+200

    6.25x=200

    x=32

    rs 200 since the questions states that if he sold it for 10 more, he would have gained 5%, 10=5% 1%=2 100%=200
