    A)  \[A\to q;\,B\to s;\,C\to r;\,D\to p\]

    B)  \[A\to r;\,B\to p;\,C\to q;\,D\to s\]

    C)  \[A\to p;\,B\to q;\,C\to r;\,D\to s\]

    D)  \[A\to r;\,B\to s;\,C\to p;\,D\to q\]

    Correct Answer: D

    Solution :

        : Simplest form of 18.75 \[\frac{18.75}{10000}=\frac{3}{16}\] : Let the number be x \[\therefore \,\,14%\] of \[x=28\] \[\frac{14}{100}\times x\,=28\] : The decimal form of 130% \[\Rightarrow \,\,\frac{130}{100}=1.30\]  \[x%\,\,\text{of}\,\frac{25}{2}\,\text{is}\,150\] is \[\frac{x}{100}\times \frac{25}{2}=150\] \[\frac{x}{8}=150\] \[x=1200\]
