    Answer : Option D

    Explanation :

    Let the amounts invested in 2002 in Companies P and Q be Rs. 8x and Rs. 9x respectively.

    Then, interest received after one year from Company P = Rs. (6% of 8x)

                                                                                             = Rs. \(\frac { 48 } { 100 } \) x 

    and interest received after one year from Company Q = Rs. (4% of 9x)

                                                                                               = Rs. \(\frac { 36 } { 100 } \)x

                                                                                        Required ratio = \(\frac { [48 /100 X]} { [36/100 X] } \) =\( \frac { 4 } { 3 } \)
