    Gain = 20%

    ∴ S.P. of A =

    ×Rs.x=Rs.

    100

    120x

    C.P.ofB=Rs.

    Answer:

    2940.3

    Step-by-step explanation:

    B sold to C at a loss of 10%= 2970

    = 2970x 10/100

    = 297

    B purchased the watch for 2970+297= 3267

    A sold the watch to B at gain of 10/100

    = 3267×10/100

    = 326.7

    Therefore cost of watch paid by A 3267-326.7

    = 2940.3
