    Let the C.P. of one orange = 1
    ∴ C.P. of 40 oranges = $ 40
    and S.P. of 40 oranges = $ 50
    ∴ Profit = (50 – 40) = $ 10

    ∴ Profit % =
    Profit
    × 100
    C.P. of 40 oranges

    Profit % =
    10
    × 100 = 25%
    40

    Second method to solve this question :
    Here, p = 50, q = 40
    Profit % = p - q× 100
    q

    Let the C.P. of one mango be Rs. 1.
    then , C.P. of 400 mangoes = Rs. 400.
    S.P. of 400 mangoes = Rs. 320.
    Loss = 400 - 320 = Rs. 80

    ∴ Loss percent =
    Loss
    × 100
    C.P. of 400 mangoes

    Correct Option: C

    Let the C.P. of one mango be Rs. 1.
    then , C.P. of 400 mangoes = Rs. 400.
    S.P. of 400 mangoes = Rs. 320.
    Loss = 400 - 320 = Rs. 80

    ∴ Loss percent =
    Loss
    × 100
    C.P. of 400 mangoes

    Loss percent =
    80
    × 100 = 20%
    400

    Let Cost price of each article is ₹ 1 .
    Cost price of 15 articles = ₹ 15
    Selling price of 15 articles = ₹ 18
    Gain = 18 - 15 = ₹ 3

    Gain % =
    Gain
    × 100
    Cost price of 15 articles

    Gain % =
    3
    × 100 = 20 %
    15

    Second method to solve this question :
    Here, p = 18, q = 15
    Gain% = p - q× 100
    q

    Correct Option: B

    Let Cost price of each article is ₹ 1 .
    Cost price of 15 articles = ₹ 15

  1. If the cost price of 15 tables be equal to the selling price of 20 tables, the loss per cent is :









  1. View Hint View Answer Discuss in Forum

    Let the cost price of one table = y
    ∴ Cost price of 15 tables = 15y and cost price of 20 tables = 20y
    According to the question ,
    Selling price of 20 tables = cost price of 15 tables = 15y
    ∴ Loss = 20y – 15y = 5y

    ∴ Loss% = 5y × 100= 25%
    20y

    Second method to solve this question :
    Here, p = 15, q = 20
    Loss% =
    p - q
    × 100
    q

    Correct Option: C

    Let the cost price of one table = y
    ∴ Cost price of 15 tables = 15y and cost price of 20 tables = 20y
    According to the question ,
    Selling price of 20 tables = cost price of 15 tables = 15y
    ∴ Loss = 20y – 15y = 5y

    ∴ Loss% = 5y × 100= 25%
    20y

    Second method to solve this question :
    Here, p = 15, q = 20
    Loss% =
    p - q
    × 100
    q

    Loss% = 15 - 20× 100
    20

    Loss% =
    -5
    × 100 = –25% (–ve sign shows loss)
    20

    Hence , Loss% = 25%

    According to question , we have
    C.P. of 3 articles = S.P. of 5 articles

    C.P.
    =
    5
    S.P.3

    Loss = S.P. - C.P. = 5 - 3 = $ 2
    Loss% =
    Loss
    × 100
    5

    Loss% = 2 × 20 = 40%
