Question

If : $\frac{5}{6}\times \frac{-7}{12}\times \frac{x}{14}$ = $\frac{5}{4}$, find $x$.

• A. -30
• B. 36
• C. -36
• D. -30

Answer 1

The correct option is C

-36

$\frac{5}{6}\times \frac{-7}{12}\times \frac{x}{14}$ = $\frac{5}{4}$

$\frac{x}{14}$ = $\frac{5\times 6\times 12}{4\times 5\times -7}$

$\Rightarrow x$ = $\frac{5\times 6\times 12\times 14}{4\times 5\times -7}$

$\Rightarrow x$ = -36
