    A)  70                               

    B)  60      

    C)  80

    Correct Answer: C

    Solution :

    Let A's income \[=Rs.\,a\] And B's income \[=Rs.\,b\]             \[a\times 60%=b\times 75%\] \[\Rightarrow \]   \[a\times 4=5\times b\,\,\,\,\,\Rightarrow \,\,\,\,\,\frac{b}{a}=\frac{4}{5}\] Now,     \[b=a\times x%\] \[\Rightarrow \]   \[x=\frac{4}{5}\times 100=80\]
