Hitesh started walking from his home. First, he walked straight from his home and took a left turn. He then walked for some more distance and took a right turn. Again, he walked some distance and took a left turn. If he is facing the North direction at the end, then in which direction did he start walking initially?

To find the initial direction, we can work backward from his final position or test the options. Here is the step-by-step breakdown:Method 1: Working BackwardIf Hitesh ended facing North, we can reverse his turns in opposite order to find where he started:Final Direction: North.Reverse the last Left turn: Instead of turning left to face North, we turn Right from North $\rightarrow$ He was facing East.Reverse the Right turn: Instead of turning right to face East, we turn Left from East $\rightarrow$ He was facing North.Reverse the first Left turn: Instead of turning left to face North, we turn Right from North $\rightarrow$ He was facing East.Initial Direction: East.Method 2: Testing Option A (East)Let's trace the path starting from the East:Start walking straight: Facing East.Take a Left turn: Now facing North.Take a Right turn: Now facing East.Take a Left turn: Now facing North.Since the final direction matches "North" as stated in the problem, East is the correct starting direction.Quick Tip for Direction ProblemsYou can also use a "Net Turn" calculation:Left (+90°) + Right (-90°) + Left (+90°) = One Net Left turn (+90°).If (Starting Direction) + (90° Left) = North, then the Starting Direction must be East.
