    One person completes \[\frac{2}{15}th\]  of the journey by train and \[\frac{9}{20}th\].  part by a car, the rest of the journey of 10 km, he travels on foot. How many km does his entire journey comprise of?

    A) 36                                

    B) 4

    C) 30                                

    D) 24

    Correct Answer: D

    Solution :

    Let the total journey be 60 km. (Multiple of 15 and 20) LCM \[(15,\,\,20)=60\] \[\therefore \]   Distance traveled by train \[=\,\,\,\,\frac{2}{15}\times 60=8\,km\] Distance traveled by car \[=\frac{9}{20}\times 60=27\,km\] Rest distance covered by foot \[=60-8-27=25\text{ }km\] But rest distance which is covered by foot is 10 km  \[\therefore \,\,\,\,\,\,\,\,25\,\,\to 10\Rightarrow \,1\to \frac{10}{25}\] \[60\to \frac{10}{25}\times 60=24\,km\] So, Total distance of his journey = 24 km
