If the map is reduced by half its original size, what would be the scale of the new map?

If the map is reduced by half its original size, it means that each unit on the reduced map represents two units on the original map. Therefore, the scale of the new map would be twice the scale of the original map. For example, if the original map had a scale of 1:50,000, the new map after being reduced by half would have a scale of 1:100,000. Similarly, if the original map had a scale of 1:100,000, the new map after being reduced by half would have a scale of 1:200,000. Based on the options given, the correct answer is 1:100,000.
