Indian Institute of Foreign Trade 2011 Solved Paper

Let 'x' be the amount invested by Aniket in share market. Therefore, amount invested by him in NSC and PPF will be 'x-20000' and 'x-40000' respectively.
It is given that, x+x−20000+x−40000=150000
⇒x=70000.
Hence, the amount invested by Aniket in NSC =x−20000=50000.
It is given that one-third of the savings made by Animesh in PPF is equal to one-half of his savings in NSC
Let 'y' be the amount invested by Animesh in NSC. Then we can say that he invested '150000-y' in PPF.
⇒

150000−y

=

y

300000−2y=3y
y=60000
Therefore, the difference between the amount invested in NSC by Animesh and Aniket =60000−50000=Rs.10000.
Hence, option D is the correct answer.
