  1. Answer:

    sʜᴇ ʙᴏᴜɢʜᴛ 9 ᴘᴇɴs.

    Step-by-step explanation:

    let the number of pens be x

    certain pens cost = rs 40

    she kept 5 pens = x-5

    She gain by selling = Rs 10

    Number of pens she bought

    = 10(x-5)=40

    = 10x-50=40

    = 10x = 40+50

    = 10x= 90

    = x = 90/10

    =9
