Q22 ans C
Q24  ans B
Q25 ans B
Q28 ans B

help with any q u know  Thanks a lot :D

Stay10:
for q7..the reason for the answer bein C is because if u compare both the supply before nd after the tax rate..u would see tht at price 20..quantity supplied after tax is 380..which if u compare with the supply before tax u ll see tht at price 17 if would be the same..therefore the difference is (20-17)=3..
hope this helps.. :)

***exam***:
yeah Thanks a lot :D

Stay10:
nytime.. :)
nd 4 the 10th question..it quite easy..firstly u need 2 use the formula 4 income elasticity of demand..
which is the % change in demand / % change in income...
so as u can see tht the income changes from 20000 to 24000..
so the % change would be constant 4 income..(4000/20000*100)..
now 4 each of the item...u can find itz change in demand..
then u ll come with the answer as B..

***exam***:
oh ya Thanks again i 4 got to take out the % form :P
