Question

x, y യുടെ 80% ആണെങ്കിൽ , 2x ന്ടെ എത്ര ശതമാനമാണ് y ?

• A. 40%
• B. 62 1/2%
• C. 66 2/3%
• D. 80%

Answer 1

Answer:

B. 62 1/2%

Given:

$x = 80\% \text{ of } y$
$x = \frac{80}{100}y = \frac{4}{5}y$

Then,

$2x = 2 \times \frac{4}{5}y = \frac{8}{5}y$

Now we need to find (y) is what percent of (2x).

$\frac{y}{2x} \times 100$

$= \frac{y}{\frac{8}{5}y} \times 100$

$= \frac{5}{8} \times 100$

$= 62.5\%$

So,

$\boxed{62.5\%}$
