Question

A period of $4$ hours $30$ min is what percent of a day?

• A. $18\frac{3}{4}\%$
• B. $20\%$
• C. $16\frac{2}{3}\%$
• D. $19\%$

Answer 1

Answer: (A)

$18\frac{3}{4}\%$

$4$ hrs $30$ min $=4\frac{1}{2}$ hrs $=\frac{9}{2}$ hrs
$\therefore$ Required $\%$ $=$ $(\frac{\frac{9}{2}}{24}\times 100)$ $\%$

$=(\frac{9}{2\times 24}\times 100)\%$
$=18\frac{3}{4}\%$
