A dishonest dealer marks up the price of his goods by 20% and gives a discount of 10% to the customer. He also uses a 900 gram weight instead of a 1 kilogram weight. Find his percentage profit due to these maneuvers?

A. 8%

B. 12%

C. 20%

D. 16%

Answer: Option C

Solution(By Examveda Team)

He sells only 900 grams when he takes the money for 1 kg.
and
he sells at a 8% profit (20% markup, 10% discount)
Hence, his selling price is Rs. 108 for 900 grams
% profit = $$\frac{{18}}{{90}} \times 100$$   = 20%

    Let cp =1000
    Sp=1080
    1000=1080, but he sold 900=1080
    Then profit 180
    P%=180/900*100=20%

    Deduction in weight : ( 100*100)/1000 = 10%
    Applying multiplying factor concept:
    100*(6/5)*(9/10)*(10/9) = 120
    So profit = ( 120 - 100 ) = 20%

    let the cost be 100rs per Kg (ie rs.100/1000g)
    he sells only 900gms means his real cost is 90rs/900gm
    his selling price is 100+20=120-12=108
    profit=108-90=18
    profit %= 18/90*100=20%answer

    Let CP = ₹ 1/gram;
    Then, he sells 900 g is ₹ 1080;
    While the CP of 900 grams is ₹ 900.
    % profit = (180*100)/900 = 20%.
