    What is the value of \[\frac{{{(2.3)}^{3}}-0.027}{{{(2.3)}^{2}}+0.69+0.09}?\]

    A) 0.3                               

    B) 2.3

    C) 1                                 

    D) 2

    Correct Answer: D

    Solution :

    \[\therefore \] \[\frac{{{(2.3)}^{3}}-0.027}{{{(2.3)}^{2}}+0.69+0.09}=\frac{{{(2.3)}^{3}}-{{(0.3)}^{3}}}{{{(2.3)}^{2}}+0.69+0.09}\] \[=\frac{(2.3-0.3)[{{(2.3)}^{2}}+{{(0.3)}^{2}}+2.3\times 0.3]}{{{(2.3)}^{2}}+0.69+0.09}\] \[=\frac{2[{{(2.3)}^{2}}0.09+0.69]}{{{(2.3)}^{2}}+0.69+0.09}=2\]
