    Here , CP of 10 kg of apples = $ 405
    As per the given in question ,
    Selling price = 405 × 110% = $ 445.50
    If 1 kg of apples were found to be rotten.
    Remaining apples = 10 – 1 = 9 kg

    Correct Option: B

    Here , CP of 10 kg of apples = $ 405

    If 1 kg of apples were found to be rotten.
    Remaining apples = 10 – 1 = 9 kg
    Therefore,

    the remaining apples (per kg) cost =
    445.50
    = $ 49.50

    Given that , CP of book = $ 400 and SP of book = $ 500
    Profit = SP of book - SP of book = 500 - 400 = $ 100

    Profit percent at C.P. =
    Profit
    × 100
    Cost Price

    Profit percent =
    100
    × 100 = 25%
    400

    Profit percent at S.P. =
    Profit
    × 100
    S.P.

    Correct Option: B

    Given that , CP of book = $ 400 and SP of book = $ 500
    Profit = SP of book - SP of book = 500 - 400 = $ 100

    Profit percent at C.P. =
    Profit
    × 100
    Cost Price

    Profit percent =
    100
    × 100 = 25%
    400

    Profit percent at S.P. =
    Profit
    × 100
    S.P.

    Profit percent at S.P. =
    100
    × 100 = 20%
    500

    ∴ Required difference = Profit percent at S.P. - Profit percent at C.P.
    ∴ Required difference = 25 – 20 = 5%

    Let the C.P. of article be Rs. y.
    According to the question,
    (104 – 103)% of y = 3
    ⇒ 1% × y = 3

    Correct Option: C

    Let the C.P. of article be Rs. y.
    According to the question,
    (104 – 103)% of y = 3
    ⇒ 1% × y = 3

    y
    = 3 ⇒ y = Rs. 300
    100


  1. If the difference between the selling prices of an article at profit of 6% and 4% is $ 3, then the cost price of the article should be :

    Suppose the cost price of article be y, then
    Given in question ,
    ( 6 - 4 ) % of y = 3
    ⇒ 2% of y = 3

    ⇒ y =
    3 × 100
    2

    Correct Option: B

    Suppose the cost price of article be y, then
    Given in question ,
    ( 6 - 4 ) % of y = 3
    ⇒ 2% of y = 3

    ⇒ y =
    3 × 100
    = $ 150

  1. The difference between the selling price and cost price of an article is $ 210. If the profit percent is 25, then the selling price of the article is









  1. View Hint View Answer Discuss in Forum

    Given in question , Selling price of an article - Cost price of an article = $ 210
    Profit% = 25%

    Profit % = 25 =
    S.P. - C.P.
    × 100
    C.P.

    210
    × 100 = 25
    C.P.

    ⇒ C.P. =
    100 × 210
    = 840
    25

    ∴ S.P. =
    125
      of 840
    100

    Correct Option: B

    Given in question , Selling price of an article - Cost price of an article = $ 210
    Profit% = 25%

    Profit % = 25 =
    S.P. - C.P.
    × 100
    C.P.

    210
    × 100 = 25
    C.P.

    ⇒ C.P. =
    100 × 210
    = 840
    25

    ∴ S.P. =
    125
      of 840
    100

    S.P. =
    840 × 125
    = $ 1050
