If 50% of x is the same as 25% of y, then x : y is equal to:

Correct option is D

Given:

If 50% of x is the same as 25% of y
Solution:
We are given that 50% of x is the same as 25% of y.
​$$\frac{50}{100} \times x = \frac{25}{100} \times y$$​​
Simplifying the equation:
​$$\frac{x}{2} = \frac{y}{4}$$​​
4x = 2y
2x = y
Thus, x : y = 1 : 2 .
