A) \[{{10}^{-\,\,1}}\]
B) \[{{10}^{-\,\,2}}\]
C) \[{{10}^{-\,\,3}}\]
D) None of these
Correct Answer: C
Solution :
[c] \[\sqrt{1369}+\sqrt{0.0615+x}=37.25\] \[\Rightarrow \] \[37+\sqrt{0.0615+x}=37.25\] \[\Rightarrow \] \[\sqrt{0.0615+x}=0.25=\frac{25}{100}=\frac{1}{4}\] \[\Rightarrow \] \[0.0615+x=\frac{1}{16}\] \[\Rightarrow \] \[0.0615\times 16+16x=1\] \[\Rightarrow \] \[\frac{615}{10000}\times 16+16x=1\] \[\Rightarrow \] \[16x=1-\frac{123}{125}=\frac{2}{125}\] \[\Rightarrow \] \[x=\frac{2}{125}\times \frac{1}{16}=\frac{1}{1000}\] \[=\frac{1}{{{(10)}^{3}}}={{10}^{-3}}\] |
