A) 840 km
B) 1600 km
C) 800 km
D) 480 km
Correct Answer: C
Solution :
Total distance \[=x\,\,\text{km}\] Then, \[\frac{2}{5}x=1200\] \[\Rightarrow \] \[x=\frac{1200\times 5}{2}=3000\] Distance travelled by car \[\left( \frac{1}{3}\times 3000 \right)=1000\,\,\text{km}\] Distance travelled by train \[=3000-(12000+1000)=800\,\,\text{km}\]You need to login to perform this action.
