A clock when seen in a mirror shows 11:25. What is the correct time?

  • A.1:25
  • B.12:35
  • C.1:35
  • D.12:25

Answer: B

A mirror reverses the dial, so a reading of \( T \) appears as \( 12{:}00 - T \) (or \( 11{:}60 - T \), which is easier to subtract).

\[ 11{:}60 - 11{:}25 = 0{:}35 \quad\Longrightarrow\quad 12{:}35 \]

Checking: 12:35 seen in a mirror does show 11:25, since the two are equally far either side of the 12.
