    Which of the following relations is true              [CPMT 1984]

    A)                 \[3Y=K(1-\sigma )\]

    B)                             \[K=\frac{9\eta Y}{Y+\eta }\]

    C)                 \[\sigma =(6K+\eta )Y\]

    D)                             \[\sigma =\frac{0.5Y-\eta }{\eta }\]

    Correct Answer: D

    Solution :

        \[Y=2\eta (1+\sigma )\Rightarrow \sigma =\frac{0.5Y-\eta }{\eta }\]
