  1. Sir,
    With due respect I beg to state that I, a student of class XII and a follower of you this blog, think there is a mistake in the answer of the question of 43.(Long Answer Type Question). Here, you have written that” n Σ r=1″ but I think it may be written like that, ” n-1 Σ r=0″ cause first value of r is 0 (1/[1=0/n]^3). So, if my statement is correct please checkout the portion of the mathematical problem.

    And a lot of thanks to you sir, for this great help. Your blog is really too helpful to me.
