    (A)

    Total cost = $80*160 + $100*40 = $16800

    Average cost per pair = $16800 / (160+40) = $84

    (B)

    (i)

    Profit % = (126-84)/84 * 100% = 50%

    (ii)

    Profit % = (63-84)/84 * 100% = -25%

    That is, Loss % = 25%

    (C)

    Overall Profit % is

    [(126*150+63*50)-16800]/16800 * 100%

    = 31.25%
