(A) 100m
(B) 1/100m
(C) 1/m
(D) 10/m
(E) 10,000/m
i understand how to get the x percent which equals x = m/100*y, but i do not know how to go further to get the answer. do i just solve for y?
e
Let y=100 and m=50.
x = m% of y = 50% of 100 = 50.
y=100 is twice the value of x=50.
Thus, y is 200% of x.
Thus, our target is 200.
Now we plug m=50 into the answers to see which yields our target of 200.
Only answer choice E works:
10,000/m = 10,000/50 = 200.
The correct answer is
E.
