    An amount of money is to be distributed among P, Q and R in the ratio of 2 : 7 : 9. The total of P's and Q's share is equal to R's share. What is the difference between the shares of P and Q?

    A)  Rs. 5000          

    B)  Rs. 7500

    C)  Rs. 9000          

    D)  Information inadequate

    Correct Answer: D

    Solution :

    Let the amount to be distributed be Rs. x. \[P:Q:R=2:7:9\] Sum of the ratios \[=2+7+9=18\] \[\therefore \]      \[P=\frac{2}{18}\times x=\frac{x}{9}\]             \[Q=\frac{7}{18}x\]             \[R=\frac{9x}{18}=\frac{x}{2}\] As Given,             \[\frac{x}{9}+\frac{7x}{18}=\frac{x}{2}\] Thus, we get no conclusion. Amount should necessarily be known.
