A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given
Explanation::
30% of x = y
or \(x = \frac{{100y}}{30}\)
or \(\frac{x}{y} = \frac{10}{3}= 3.33..\)
Hence Qty A > Qty B

GIVEN: 30 percent of x is y.
We can write: 0.3x = y
From here, we can use the technique of matching operations
Given:
Quantity A: x/y
Quantity B: 3
Since we're told that y is POSITIVE, we can safely multiply both quantities by y to get:
Quantity A: x
Quantity B: 3y
Since we know that 0.3x = y, we can replace y with 0.3x to get:
Quantity A: x
Quantity B: 3(0.3x)
Simplify to get:
Quantity A: x
Quantity B: 0.9x
Since we're told that x is POSITIVE, we can safely divide both quantities by x to get:
Quantity A: 1
Quantity B: 0.9
Answer: A
