    The value of \[\frac{{{(0.03)}^{2}}-{{(0.01)}^{2}}}{0.03-0.01}\] is

    A) 0.02                             

    B) 0.004    

    C) 0.4                   

    D) 0.04

    Correct Answer: D

    Solution :

    \[\frac{{{(0.03)}^{2}}-{{(0.01)}^{2}}}{0.03-0.01}\] \[[Using\,\,{{a}^{2}}-{{b}^{2}}=(a+b)(a-b)]\] \[=\frac{(0.03+0.01)(0.03-0.01)}{0.03-0.01}\] \[=0.03+0.01=0.04\]
