Question

In an office, the working hours are 10.30 AM to 5.30 PM. In between, 30 minutes are spent on lunch. Find the ratio of office hours to the time spent for 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 AM to 5.30 PM
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).
