  1. View Hint View Answer Discuss in Forum

    Given that , Selling Price of 12 kg of potatoes = Rs. 63

    C.P. of 12 kg of potatoes = Rs.63 × 100= Rs. 60
    105

    ∴ C.P. of 50 kg of potatoes =
    60
    		 × 50 = Rs. 250
    12

    S.P. of 50 kg of potatoes = Rs. 247.50

    Correct Option: A

    Given that , Selling Price of 12 kg of potatoes = Rs. 63

    C.P. of 12 kg of potatoes = Rs.63 × 100= Rs. 60
    105

    ∴ C.P. of 50 kg of potatoes =
    60
    		 × 50 = Rs. 250
    12

    S.P. of 50 kg of potatoes = Rs. 247.50
    Loss = C.P. of 50 kg of potatoes - S.P. of 50 kg of potatoes
    Loss = Rs. (250 – 247.50) = Rs. 2.5
    ∴ Loss percent =
    2.5
    		 × 100 = 1%
    250

    Let the C.P. of article be Rs. y.
    According to the question,

    y × 105
    		 -
    y × 80
    		 = 200
    100100

    ⇒ 105y – 80y = 20000
    ⇒ 25y = 20000
    ⇒ y =
    20000
    		 = Rs. 800
    25

    Using the given formula :
    Here, a = 20%, R = 200, b = 5%
    C.P. =
    R × 100
    b + a

    Correct Option: A

    b + a

    C.P. =
    100 × 200
    20 + 5

    C.P. =
    100 × 200
    		 = Rs. 800

  1. View Hint View Answer Discuss in Forum

    From question CP/SP = 12/18 = 2/3
    ∴ Profit (%) = ( 3 - 2 ) / 2 x 100

    Correct Option: B

    From question CP/SP = 12/18 = 2/3
    ∴ Profit (%) = ( 3 - 2 ) / 2 x 100 = 50%

    2nd Solution:
    CP = 100/18 = 5.55 paisa
    SP = 100/12 = 8.33 paisa
    ∴ Profit = (8.33-5.55)/5.55 x 100 = 50 %
