$$\frac{3}{4}$$ : $$\frac{1}{2}$$ :: 27y : ? Solve this -
Answer & Solution
Correct Answer:
Option
B
Let the missing number be x.
Then,
$$\eqalign{ & = \frac{1}{3}:\frac{1}{2}::27y:x \cr & \Rightarrow \frac{3}{4}x = \frac{1}{2} \times {\text{27}}y \cr & \Rightarrow x{\text{ = }}\frac{{27y}}{2} \times \frac{4}{3} \cr & = 18y \cr} $$
Then,
$$\eqalign{ & = \frac{1}{3}:\frac{1}{2}::27y:x \cr & \Rightarrow \frac{3}{4}x = \frac{1}{2} \times {\text{27}}y \cr & \Rightarrow x{\text{ = }}\frac{{27y}}{2} \times \frac{4}{3} \cr & = 18y \cr} $$
