Question

In an office, the working hours are 10:30 A.M. to 5:30 P.M. In between this time, 30 minutes are spent on lunch. Find the ratio of time spent in office to the time spent on lunch.

• A. 7 : 30
• B. 1 : 14
• C. 14 : 1
• D. 30 : 7

Answer 1

The correct option is C

14 : 1

Office hours = 10:30 A.M. to 5:30 P.M.
The number of hours spent in office = 7

It is given that 30 minutes is spent on lunch.

Thus, number of hours spent on lunch = $\frac{30}{60}=\frac{1}{2}$

$\therefore \text{required ratio}=7:\frac{1}{2}$

$=\frac{7}{\frac{1}{2}}$ (In terms of fractions)

$=\frac{14}{1}$

$=14:1$ (Converting back to the ratio form).
