    Q#1 Answer: (A) Elasticity of demand is influenced by the time elapsed since a price change. The time frame within which the supply decision is made and the ability to substitute productive resources are factors that influence elasticity of supply.

    ================================================== ================================================== =======
    Today's Q (Question provided by Elan Guides)

    Q#2: A good has a price elasticity of demand of 1.2. In response to an increase in price of 30%, quantity demanded will change from 150 units to:

    A. 104.24
    B. 195.76
    C. 96

    I disagree that it is A

    Demand should logically drop by 36% which is 54 and the answer should be 96..Basically increase in price by 30% makes demand go down by 1.2*30% = 36%

    To fundamentally understand look at it as an equation of a line Y = mx+c with c = 0 here as Price and demand have an inverse relation and hence the slope which is price elasticity of demand is -ve 1.2 so and as 1.2 is the price elasticity of demand basically

    (demand1-demand2)/ (price1 - price 2) => y is demand here so based on Y=mx => demand drop is -1.2*30% = 36%..Sorry my explanation is mathematical in nature as my mind understands economics thru mathematics

    Q#2 Answer: (C) Price elasticity of demand = % change in Q / % change in price
    -1.2 = x / 30%, x = -36%
    -36% = (x - 150) / 150 giving x = 96.
    Great explanation, Shiva

    I think the consumer surplus should equal producer surplus.
