A man travels the distance of his journey 3/4 by bus, 1/6 by rickshaw and remaining 2 km on foot. The total distance travelled by the man is :

Answer: Option D

Let the man travels 1 unit distance
So, remaining distance
$$\begin{array}{rl}& =1-\left(\frac{1}{6}+\frac{3}{4}\right)\\ & =1-\frac{22}{24}\\ & =\frac{1}{12}\\ & \because \frac{1}{12}\text{ unit}=\text{2 km}\\ & \text{So, 1 unit}=24\text{ km}\end{array}$$
