    The cost price of an article is times of its selling price. Find the loss or the gain as percent.
    Ans : Let S.P. = 1
    C.P. = 4/5 × 1 = 4/5
    ∴ Gain = S.P. - C.P. [∵ Gain = S.P. - C.P.]
    = 1 - 4/5
    = (5 - 4)/5
    = 1/5
    ∴ Gain % = Gain/C.P. × 100
    = (1/5)/(4/5) × 100
    = (1/5)/( 4/5) × 100
    = 1/5 × 5/4 × 100
    = 25%
