When a number is added to a second number, the sum is $333\frac{1}{3}$ percent of the second number. What is the ratio between the first number to the second number?
A3 : 7
B7 : 4
C7 : 3
DData inadequate

Correct answre is: 7 : 3

Explanation:

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

 

x + y =  \(333\frac{1}{3}\) % of y

\(x + y = \frac{1000}{3 \times 100}y\)

\(x+y = \frac{10}{3}y\)

3x + 3y = 10y
3x = 7y

\( \frac{x}{y}=\frac{7}{3}= 7 : 3\)
