A) 20 km
B) 21 km
C) 22 km
D) 24 km
Correct Answer: C
Solution :
Let the distance of office be\[x\]km. \[\therefore \] \[\frac{x}{24}-\frac{x}{30}=\frac{11}{60}\] \[\Rightarrow \] \[\frac{5x-4x}{120}=\frac{11}{60}\Rightarrow \frac{x}{120}=\frac{11}{60}\] \[\Rightarrow \] \[x=\frac{11}{60}\times 120=22\]km.You need to login to perform this action.
