A) 25
B) \[\frac{1}{\sqrt{25}}\]
C) \[\sqrt{25}\]
D) \[\frac{1}{25}\]
Correct Answer: C
Solution :
\[\frac{100\sqrt{25}}{\sqrt{25}+x}=50\] or \[\frac{100\times 5}{5+x}=50\] or \[500=250+50x\] or \[50x=250\] \[\therefore \] \[x=\frac{250}{50}\] \[=5=\sqrt{25}\]You need to login to perform this action.
