    Marked price of article = 80 + 40 = Rs. 120
    If the discount be x%, then
    x% of 120 = Rs. 40

    ⇒ 
    120 × x
    = 40
    100

    ⇒  x =
    40 × 100
    =
    100
    =
    100
    = 33.33%
    12033

    Correct Option: D

    Marked price of article = 80 + 40 = Rs. 120
    If the discount be x%, then
    x% of 120 = Rs. 40

    ⇒ 
    120 × x
    = 40
    100

    ⇒  x =
    40 × 100
    =

    130x
    100

    = Rs.
    13x
    10

    According to the question,
    13x
    =
    85
    = 910
    10100

    ⇒  13x × 85 = 910 × 1000
    ⇒  x =
    910000
    = Rs. 823.5
    13 × 85

    Profit on outlay = Rs. 6000
    According to the question,
    25% of outlay = Rs. 6000

    ∴  Outlay =
    6000 × 100
    = Rs. 24000
    25

    Again, if the advertised price be Rs. x, then
    x ×
    80
    = Rs. (24000 + 6000)
    100

    ⇒  x =
    30000 × 100
    = Rs. 37500
    80

    Correct Option: B

    Let the marked price of building be Rs. z.
    ∴  According to the question,
    z × (100 – x)% = y

    ⇒  z ×
    100 − x
    = y
    100

    ⇒  z = Rs.
    100y
    100 − x

    Second Method :
    S.P. = Rs. y, D = x %
    M.P. =
