    As per the given in question ,
    S.P. of 36 oranges = C.P. of 36 oranges – S.P. of 4 oranges
    ⇒ S.P. of 40 oranges = C.P. of 36 oranges

    ∴ Loss percent =
    4
    × 100 = 10%
    40

    We can find the required answer with the help of given method :
    Here, p = 36, q = 4
    Loss % =
    q × 100
    p + q

    Correct Option: C

    As per the given in question ,
    S.P. of 36 oranges = C.P. of 36 oranges – S.P. of 4 oranges
    ⇒ S.P. of 40 oranges = C.P. of 36 oranges

    ∴ Loss percent =
    4
    × 100 = 10%
    40

    We can find the required answer with the help of given method :
    Here, p = 36, q = 4
    Loss % =

    = 10%
    36 + 4

    Let the C.P. for Mr. X = Rs. y
    According to the question,

    100 + 100% of y = 5000
    9

    ⇒ y ×
    1000
    = 5000
    900

    ⇒ y =
    5000 × 900
    = Rs. 4500
    1000

    Correct Option: A

    Let the C.P. for Mr. X = Rs. y
    According to the question,

    100 + 100% of y = 5000
    9

    ⇒ y ×
    1000
    = 5000
    900

    ⇒ y =
    5000 × 900
    = Rs. 4500
    1000

    ∴ C.P. for Mr. X = Rs. 4500
    ∴ Discount = Rs. (5000 – 4500) = Rs. 500
    ∴ Discount percent =
    500
    × 100 = 10%
    5000


  1. Profit after selling a commodity for $ 524 is the same as loss after selling it for $ 452. The cost price of the commodity is









  1. View Hint View Answer Discuss in Forum

    Let the cost price of the commodity = $ y
    According to the question ,
    524 – y = y – 452
    ⇒ 2y = 524 + 452
    ⇒ 2y = 976

    ⇒ y =
    976
    2

    Correct Option: C

    Let the cost price of the commodity = $ y
    According to the question ,
    ⇒ 524 – y = y – 452
    ⇒ 2y = 524 + 452
    ⇒ 2y = 976

    ⇒ y =
    976
    = 488
    2

    The required price = $ 488



  1. A clock was sold for $ 144. If the percentage of profit was numerically equal to the cost price, the cost of the clock was

    Given that , Selling price of the clock = $ 144
    Let the cost price be y.
    According to question ,
    ∴ (100 + y)% of y = 144
    ⇒ (100 + y)y = 14400
    ⇒ y2 + 100y – 14400 = 0
    ⇒ y2 + 180y – 80y – 14400 = 0
    ⇒ y(y + 180) – 80 (y + 180) = 0

    Correct Option: B

    Given that , Selling price of the clock = $ 144
    Let the cost price be y.
    According to question ,
    ∴ (100 + y)% of y = 144
    ⇒ (100 + y)y = 14400
    ⇒ y2 + 100y – 14400 = 0
    ⇒ y2 + 180y – 80y – 14400 = 0
    ⇒ y(y + 180) – 80 (y + 180) = 0
    ⇒ (y + 180) (y – 80) = 0
    ⇒ y = 80 [y ≠ –180]
    Hence , required answer is $ 80.
