    \[\frac{3.25\times 3.25+1.75\times 1.75-2\times 3.25\times 1.75}{3.25\times 3.25-1.75\times 1.75}\]

    A) \[0.5\]                          

    B)  \[0.4\]

    C)  \[0.3\]                  

    D)       \[0.2\]

    Correct Answer: C

    Solution :

     If \[3.25=x\]and \[1.75=y\]then, Expression \[=\frac{{{a}^{2}}+{{b}^{2}}-2ab}{{{a}^{2}}-{{b}^{2}}}\] \[=\frac{{{(a-b)}^{2}}}{(a+b)\,(a-b)}=\frac{a-b}{a+b}\] \[=\frac{3.25+1.75}{3.25+1.75}=\frac{15}{5}=0.3\]
