Question

What is the value of 20 percent of x?
(I) 1/4 of 20 percent of x is 5
(II) $4x=S,5y=S$ and $y=80$

• A. Statement (I) alone is sufficient, but statement (II) alone is not sufficient.
• B. Statement (II) alone is sufficient, but statement (I) alone is not sufficient.
• C. Both statements together are sufficient, but neither statement alone is sufficient.
• D. Each statement alone is sufficient.

Answer 1

The correct option is D Each statement alone is sufficient.

(I) $\Rightarrow \frac{1}{4}$ of 20% of $x=5\Rightarrow$ 20% of x = 20
(II) $\Rightarrow S=400\Rightarrow x=100\Rightarrow$20% of x = 20
$\therefore$ Each statement alone is sufficient.
