Concept:Reducing the map to half its original size makes each unit on the new map represent twice the ground distance.
Explanation:The original scale of the NITY DISTRICT map is
1:50,000.
This means 1 unit on the original map represents
50,000 units on the ground.
When the map is reduced to half, the length of the map becomes half of the original.
So, 1 unit on the new map corresponds to 2 units on the old map.
Therefore, 1 unit on the new map represents
2×50,000=100,000 units on the ground.
Hence, the new Representative Fraction is
1:100,000.
Answer:C.
1:100,000
