    Question 14 of iai paper, April 2008 , part b has solution of integrating the f(x.y) from 0 to 20, while the limit of x is from 10 to y, and the question asks for x> 20.

    Why did this happen that we take from 0 to 20? Is it an error or is there some reason behind it?.

    Thank you,
    Shyam

    There is a mistake in limits of the integral, however you will see that if you calculate with the correct limits you still get the answer they give of 5/9.
