    Answer : Option D

    Explanation :

    Let Rs. x lakhs be invested in Company P in 2000, the amount invested in Company Q in 2000 = Rs. (30 - x) lakhs.

    Total interest received from the two Companies after 1 year

          = Rs. [(7.5% of x) + {9% of (30 - x)}] lakhs

         = Rs. [2.7 - \((\frac { 1.5X } { 100 } )\) ] lakhs

         = [ 2.7 - \((\frac { 1.5X } { 100 } )\)] = 2.43  x = 18
