Question

A lunch interval of half an hour is$5\%$ of total office hours. Calculate the total office hours​.

Answer 1

Here given that interval of half an hour out of total office hour is lunch break

and it is given that $\frac{1}{2}hour$ is equal to $5\%$ of total working hour

Let the total working hour is $xhours$

then according to given information we have

$\begin{array}{rcl}\frac{5}{100}\times x& =& \frac{1}{2}\\ & \Rightarrow & \frac{5}{100}\times x=\frac{1}{2}\\ & \Rightarrow & x=\frac{1\times 100}{2\times 5}\\ & \Rightarrow & x=10\end{array}$

Hence, total working hour of office is $10hours$
