A) 0.081
B) 0.810
C) 0.081
D) 8.09
Correct Answer: C
Solution :
(c): \[\sqrt{0.9\times 0.09\times x}=0.9\times 0.09\times \sqrt{z}\] \[\Rightarrow \frac{\sqrt{x}}{\sqrt{z}}\text{=}\frac{0.9\times 0.09}{\sqrt{0.9\times 0.09}}\] Squaring, \[\frac{x}{z}=\frac{{{\left( 0.9\times 0.09 \right)}^{2}}}{0.9\times 0.09}=0.9\times 0.09=0.081.\]You need to login to perform this action.
