The ratio of price elasticity of supply of a commodity A and B is 1:1....
Solution:
Given:
Price elasticity of supply of A and B = 1:1.5
Percentage fall in price of A = 20%
Resultant fall in supply of A = 40%
Initial price of B = Rs.10
Final price of B = Rs.11
To find:
The percentage increase in supply of B
Calculations:
Let's assume that the initial supply of A is 100 units.
As per the given information, a 20% fall in the price of A leads to a 40% fall in its supply.
Therefore, the new price of A = 0.8 * initial price of A = 0.8 * P
And the new supply of A = 0.6 * initial supply of A = 0.6 * 100 = 60 units
Now, we know that the ratio of price elasticity of supply of A and B is 1:1.5
Let's assume that the price elasticity of supply of A is x and the price elasticity of supply of B is 1.5x.
Hence, we can write:
Elasticity of supply of A / Elasticity of supply of B = 1/1.5
x / 1.5x = 1/1.5
x = 2.25x/3
x = 0.75x
Therefore, the price elasticity of supply of A is 0.75 and the price elasticity of supply of B is 1.5 * 0.75 = 1.125
Now, we can use the formula of price elasticity of supply to find the percentage increase in supply of B:
% change in quantity supplied of B = Price elasticity of supply of B * % change in price
where % change in price = (final price - initial price) / initial price * 100
= (11-10) / 10 * 100 = 10%
% change in quantity supplied of B = 1.125 * 10
= 11.25%
Therefore, the percentage increase in supply of B is 11.25%.
Conclusion:
The percentage increase in supply of B if its price rises from Rs.10 to Rs.11 is 11.25%.
The ratio of price elasticity of supply of a commodity A and B is 1:1....
For A,
Fall in price = 20%
Fall in supply = 40%
Change in supply is twice the change in price.
Elasticity of A = 2
The ratio is given as 1:1.5
multiply the ratio by 2 so that elasticity of A matches with first place of ratio.
New ratio after multiplied by 2= 2:3
therefore elasticity of B=3
For b ,
change in price = 11-10=1
% change in price = 10%
therefore
% change in quantity supplied= elasticity × %change in price = 3×10 = 30%
