A) 1
B) 2
C) 3
D) 4
Correct Answer: C
Solution :
\[x\propto y\] and \[x\propto \frac{1}{{{z}^{2}}}\] \[x\propto \frac{y}{{{z}^{2}}}\,\,\Rightarrow \,\,x=k\frac{y}{{{z}^{2}}}\] \[6=k\times \frac{75}{{{(5)}^{2}}}\Rightarrow \,k=2\] Again, \[x=2\times \frac{24}{{{(4)}^{2}}}\,\Rightarrow \,x=3\]You need to login to perform this action.
