Let's re-evaluate the problem step by step and verify the correct direction.

  1. Starting Position: East (0 degrees).

  2. First Turn (Clockwise 48 degrees):

    • From East (0 degrees), moving clockwise 48 degrees.
      • East (0 degrees) + 48 degrees = 48 degrees.
    • 48 degrees is between East (0 degrees) and South-East (90 degrees).
  3. Second Turn (Anti-clockwise 72 degrees):

    • From the new position (48 degrees), turning 72 degrees anti-clockwise:

      • 48 degrees - 72 degrees = -24 degrees.
    • Since -24 degrees can be re-expressed in a 360-degree system:

      -24 degrees + 360 degrees = 336 degrees.

    • 336 degrees is equivalent to 360 - 336 = 24 degrees in the clockwise direction from North.

Evaluating:

  • North is 0 degrees.
  • East is 90 degrees.
  • 24 degrees clockwise from North falls between North and East.

Hence, the final direction is:

Correct Answer: North-East
