A) 31.2 km
B) 38.4 km
C) 32.8 km
D) 24 km
Correct Answer: D
Solution :
Let total Journey = x km Then, remaining Journey on cycle \[=\left[ 1-\left( \frac{2}{15}+\frac{9}{20} \right) \right]x\] \[=\frac{5}{12}x\] Now, \[\frac{5}{12}x=10\] \[x=\frac{10\times 12}{5}\] \[\Rightarrow \] \[x=24\,\,km\]You need to login to perform this action.
