C) 4
D) 25
Correct Answer: D
Solution :
Let the value of * be x \[\therefore \] \[\frac{50}{x}=\frac{x}{12\frac{1}{2}}\] \[\Rightarrow \] \[\frac{50}{x}=\frac{2x}{25}\] \[\Rightarrow \] \[2{{x}^{2}}=0.50\times 25\] \[\Rightarrow \] \[{{x}^{2}}=25\times 25\] \[\therefore \] \[x=25\]You need to login to perform this action.
