A) 39
B) 36
C) 54
D) 26
Correct Answer: D
Solution :
Let \[\frac{13}{19}\,=\frac{x}{y}\] (fraction form) \[\Rightarrow \] \[13y=18y\] \[\Rightarrow \] \[y=\frac{18}{13}x\]. Product = 936 \[\frac{18}{13}{{x}^{2}}=936\] \[{{x}^{2}}=\frac{{{\bcancel{938}}^{52}}\times 13}{{{\bcancel{18}}_{1}}}\] \[{{x}^{2}}=52\times 13\] \[x=\sqrt{13\times 13\times 2\times 2}\] \[x=26\]
