  1. A shopkeeper fixes the price of an article at 30% higher than its actual cost. If the sells it at 10% discount on marked price then, the profit is :








  1. View Hint View Answer Discuss in Forum

    Let the C.P. of article be Rs. 100.
    ∴  Marked price = Rs. 130

    S.P. =
    130 × 90
    		 = Rs. 117
    100

    ∴ Profit% = 17%
    OR
    Required profit percent = x + y +
    xy
    		%
    100

    = 30 − 10 −
    30 × 10
    		% = 17%
    100

    Second Method :
    Here, r = 30%
    r1 = 10%
    Profit % =
    r × (100 − r1)
    		 − r1
    100

    =
    30 × (100 − 10)
    		 − 10
    100

    =
    30 × 90
    		− 10 = 17%
    100

    Correct Option: C

    Let the C.P. of article be Rs. 100.
    ∴  Marked price = Rs. 130

    S.P. =
    130 × 90
    		 = Rs. 117
    100

    ∴ Profit% = 17%
    OR
    Required profit percent = x + y +
    xy
    		%
    100

    = 30 − 10 −
    30 × 10
    		% = 17%
    100

    Second Method :
    Here, r = 30%
    r1 = 10%
    Profit % =
    r × (100 − r1)
    		 − r1
    100

    =
    30 × (100 − 10)
    		 − 10
    100

    =
    30 × 90
    		− 10 = 17%

  1. The marked price of a CD is Rs. 250. It is sold for Rs. 225. The rate of discount is :








  1. View Hint View Answer Discuss in Forum

    Marked price = Rs. 250
    S.P. = Rs. 225
    Discount = 250 – 225 = Rs. 25
    If the rate of discount be x%, then

    250 × x
    		 = 25
    100

    ⇒  x =
    25 × 100
    		 = 10%
    250

    Second Method : Here, M.P. = Rs. 250, S.P. = Rs. 225
    Discount % =
    M.P. − S.P.
    		 = 100%
    M.P.

    =
    250 − 225
    		 × 100% = 10%
    250

    Correct Option: B

    Marked price = Rs. 250
    S.P. = Rs. 225
    Discount = 250 – 225 = Rs. 25
    If the rate of discount be x%, then

    250 × x
    		 = 25
    100

    ⇒  x =
    25 × 100
    		 = 10%
    250

    Second Method : Here, M.P. = Rs. 250, S.P. = Rs. 225
    Discount % =
    M.P. − S.P.
    		 = 100%
    M.P.

    =
    250 − 225
    		 × 100% = 10%
    250
