X equals to Y% of what number?
Let the number y% of which is x be z:
Basically we need to calculate the ratio \(\frac{x}{y}\).
(1) x = 3y:
Sufficient.
(2) 6y + 2x = 56x/14:
Sufficient.
Answer: D.
Let the number y% of which is x be z:
- \(\frac{y}{100}*z=x\);
\(z=\frac{100x}{y}\).
Basically we need to calculate the ratio \(\frac{x}{y}\).
(1) x = 3y:
- \(\frac{x}{y}=3\).
Sufficient.
(2) 6y + 2x = 56x/14:
- \(6y+2x=4x\);
\(6y=2x\);
\(\frac{x}{y}=3\).
Sufficient.
Answer: D.
