1.two houses are bought for rupees 65000 each. the first is sold at a profit of 8% . if the average price received for each house is rupees 66300,find the gain or loss % on the second house.

2. a shopkeeper sells sugar in such a way that the selling price of 950gm is the same as the cost price of 1kg. find his gain %.

  • maths -

    P1 = 1.08*65000 = 70200.
    (P1+P2)/2 = 66,300
    (70,200+P2)/2 = 66300
    70200+P2 = 132,600
    P2 = 62400
    Loss = 65000-62400 = 2600
    %Loss = 2600/65000 = 0.04 = 4%.

    2. 1kg/0.95kg = 1.0526 = 105.26 %.
    %Gain = 105.3% - 100% = 5.3%.
