If 25% of first number is three times 50% of second number then what is the ratio of the first number to the second number?

Correct option is D

Given:

25% of first number = 3 × (50% of second number)

Formula Used:

Percentage of a number =$$\frac {\text{Percentage}}{100}$$​× Number

Solution:

Let the first number be 'x' and the second number be 'y'.

According to the given condition:

​$$\frac{25}{100}$$​× x = 3 × $$\frac{50}{100}$$​ × y

​$$\frac 14$$​ × x = 3 × $$\frac 12$$​× y

x = $$\frac {12}{2}$$​× y

​$$\frac x y = \frac 6 1$$​​

x : y = 6 : 1
