If 50% of a certain number is equal to 3/4 th of another number, what is the ratio between the numbers?

A3 : 2

B2 : 5

C5 : 2

D3 : 4

Nithin ? undefined

Correct answer is: 3 : 2

Explanation:

Let, First number = x
Second number = y

\(\therefore x \times \frac{50}{100}=y \times \frac{3}{4}\)

\(\implies \frac{x}{2}=y \times \frac{3}{4}\)

\(\implies \frac{x}{y}=\frac{3}{4} \times 2=\frac{3}{2} \text{ or}\ 3 : 2\)
