Question

In an office, the working hours are $10:30\text{AM}$ to $5:30\text{PM}$ and in between $30\text{min.}$ 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 are from $10:30\text{AM}$ to $5:30\text{PM}$ i.e. $7\text{hrs}$ that is equal to $420\text{min.}$

And, the lunch time is equal to $30\text{min.}$

So, the required ratio will be,

$\Rightarrow 420:30$

$\Rightarrow 14:1$
