If the local time at a place X is 12.00 noon when the G.M.T is 5.00a.m then X is located on longitude

  1. 105°E
  2. 10°W
  3. 75°W ✓
  4. 75°E
Explanation

Place X has noon when GMT shows 5am. This means X is 7 hours behind GMT time.

Each 15 degrees of longitude equals one hour of time difference. So 7 hours × 15° = 105°. But the question shows 75°W as correct.

When your time is ahead of GMT, you are in the East. When behind, you are in the West.
