# Moderate Time, Speed & Distance Solved QuestionAptitude Discussion

 Q. A train left station $X$ at $A$ hour $B$ minutes. It reached station $Y$ at $B$ hour $C$ minutes on the same day, after travelling $C$ hours $A$ minutes (clock shows time from 0 hours to 24 hours). Number of possible value(s) of $A$ is:
 ✔ A. 0 ✖ B. 1 ✖ C. 2 ✖ D. 3

Solution:

$A$ hours + $C$ hours = $B$ hours -------- (i)

$A$, $C$ and $B$ cannot have values greater than or equal to 24

$B$ minutes + $A$ minutes = $C$ minutes -------- (ii)

Looking at the two equations, we get that no value of $A$ satisfies both the equations.
Hence, option A
