The expression "x is what percent of y" can mathematically be written as x = p% of y, where p is the answer.M7MBA wrote:If y > 0, then x is what percent of y?
(1) y = 5x
(2) x = 5
The OA is the option A.
How can I know the percent that x represents? Experts, may you help here? Thanks in advanced.
Thus, x = p%*y => x = py/100 => p = (x/y)*100
If we get the value of x/y, we get the answer.
Let's take each statement one by one.
(1) y = 5x
=> x/y = 1/5. Sufficient.
(2) x = 5
We do not have any information about y. Insufficient.
The correct answer: A
Hope this helps!
