1. S.P. of each buffalo = ₹ 20,000 S.P. of two buffaloes = ₹ 20,000 x 2 = ₹ 40,000 One buffalo is sold at 5% gain. Let C.P. be ₹ 100, then S.P. = 100 + 5 = ₹105 ∵ When S.P. is ₹ 105, then C.P. = ₹ 100 ∴ When S.P. is ₹ 1, then C.P. = 100/105 ∴ When S.P. is ₹ 20,000, then C.P. = 100/105 x 20000 = ₹ 19,04Read more

    S.P. of each buffalo = ₹ 20,000
    S.P. of two buffaloes = ₹ 20,000 x 2 = ₹ 40,000
    One buffalo is sold at 5% gain.
    Let C.P. be ₹ 100, then S.P. = 100 + 5 = ₹105
    ∵ When S.P. is ₹ 105, then C.P. = ₹ 100
    ∴ When S.P. is ₹ 1, then C.P. = 100/105
    ∴ When S.P. is ₹ 20,000, then C.P. = 100/105 x 20000 = ₹ 19,047.62
    Another buffalo is sold at 10% loss.
    Let C.P. be ₹ 100, then S.P. = 100 – 10 = ₹ 90
    ∵ When S.P. is ₹ 90, then C.P. = ₹ 100
    ∴ When S.P. is ₹ 1, then C.P. = 100/90
    ∴ When S.P. is ₹ 20,000, then C.P. = 100/90×20000 = ₹ 22,222.22
    Total C.P. = ₹ 19,047.62 + ₹ 22,222.22 = ₹ 41,269.84
    Since C.P. > S.P. Therefore here it is loss.
    Loss = C.P. – S.P. = ₹ 41,269.84 – ₹ 40,000.00 = ₹ 1,269.84

  2. Rate of discount on all items = 10% Marked Price of a pair of jeans = ₹ 1450 and Marked Price of a shirt = ₹ 850 Discount on a pair of jeans = Rate X M.P./100 = 10 X 1450/100 = ₹ 145 ∴ S.P. of a pair of jeans = ₹ 1450 – ₹ 145 = ₹ 1305 Marked Price of two shirts = 2 x 850 = ₹ 1700 Discount on two shiRead more

    Rate of discount on all items = 10%
    Marked Price of a pair of jeans = ₹ 1450 and Marked Price of a shirt = ₹ 850
    Discount on a pair of jeans = Rate X M.P./100 = 10 X 1450/100 = ₹ 145
    ∴ S.P. of a pair of jeans = ₹ 1450 – ₹ 145 = ₹ 1305
    Marked Price of two shirts = 2 x 850 = ₹ 1700
    Discount on two shirts = Rate X M.P./100 = 10X1700/100 = ₹ 170
    ∴ S.P. of two shirts = ₹ 1700 – ₹ 170 = ₹ 1530
    Therefore, the customer had to pay = 1305 + 1530 = ₹ 2,835

  3. Cost price of VCR = ₹ 8000 and Cost price of TV = ₹ 8000 Total Cost Price of both articles = ₹ 8000 + ₹ 8000 = ₹ 16,000 Now VCR is sold at 4% loss. Let C.P. of each article be ₹ 100, then S.P. of VCR = 100 – 4 = ₹ 96 ∵ When C.P. is ₹ 100, then S.P. = ₹ 96 ∴ When C.P. is ₹ 1, then S.P. = 96/100 ∴ WheRead more

    Cost price of VCR = ₹ 8000 and Cost price of TV = ₹ 8000
    Total Cost Price of both articles = ₹ 8000 + ₹ 8000 = ₹ 16,000
    Now VCR is sold at 4% loss.
    Let C.P. of each article be ₹ 100, then S.P. of VCR = 100 – 4 = ₹ 96
    ∵ When C.P. is ₹ 100, then S.P. = ₹ 96
    ∴ When C.P. is ₹ 1, then S.P. = 96/100
    ∴ When C.P. is ₹ 8000, then S.P. = 96/100×8000 =₹ 7,680
    And TV is sold at 8% profit, then S.P. of TV = 100 + 8 = ₹ 108
    ∵ When C.P. is ₹ 100, then S.P. = ₹ 108
    ∴ When C.P. is ₹ 1, then S.P. = 108/100
    ∴ When C.P. is ₹ 8000, then S.P. = 108/100 = ₹ 8,640
    Then, Total S.P. = ₹ 7,680 + ₹ 8,640 = ₹ 16,320
    Since S.P. > C.P.,
    Therefore Profit = S.P. – C.P. = 16320 – 16000 = ₹ 320
    And Profit% = Profit/Cost Price x 100 = 320/16000 x 100 = 2%

  5. No. of articles = 80 Cost Price of articles = ₹ 2,400 And Profit = 16% ∵ Cost price of articles is ₹ 100, then selling price = 100 + 16 = ₹ 116 ∴ Cost price of articles is ₹ 1, then selling price = 116/100 ∴ Cost price of articles is ₹ 2400, then selling price = 116/100x2400 = ₹ 2784 Hence, SellingRead more

    No. of articles = 80
    Cost Price of articles = ₹ 2,400
    And Profit = 16%
    ∵ Cost price of articles is ₹ 100, then selling price = 100 + 16 = ₹ 116
    ∴ Cost price of articles is ₹ 1, then selling price = 116/100
    ∴ Cost price of articles is ₹ 2400, then selling price = 116/100×2400 = ₹ 2784
    Hence, Selling Price of 80 articles = ₹ 2784
    Therefore Selling Price of 1 article = 2784/80 = ₹ 34.80
