A) 2 : 3
B) 3 : 2
C) 4 : 3
D) 3 : 4
Correct Answer: D
Solution :
Speed of car = x km/h and speed of bus = y km/h According to question, \[\frac{120}{x}+\frac{480}{y}=8\] ?(i) \[\frac{200}{x}+\frac{400}{y}=8\frac{1}{3}\] ?(ii) By solving Eqs. (i) and (ii), we get \[15y+60x=24y+48x\] \[\therefore \] \[12x=9y\Rightarrow \frac{x}{y}=\frac{3}{4}\]You need to login to perform this action.
