| When a number is added to a second number, the sum is \[333\frac{1}{3}%\]of the second number. What is the ratio between the first number to the second number? |
A) 3 : 7
B) 7 : 4
C) 7 : 3
D) Data inadequate
E) None of these
Correct Answer: C
Solution :
| Let the first number be x and the second number be y. |
| Then, \[x+y=338\frac{1}{3}\]% of y |
| \[\Rightarrow \] \[x+y=\frac{1000}{3\times 100}y\] |
| \[\Rightarrow \] \[x+y=\frac{10}{3}y\]\[\Rightarrow \]\[x=\frac{7}{3}y\] |
| \[\therefore \] \[\frac{x}{y}=\frac{7}{3}\] |
