Question

Which of the following scale is the smallest one?

• A. 1 cm = 50 m
• B. 4: 200000
• C. RF = 1/50000
• D. 1 cm = 5000 m

Answer 1

The correct option is D 1 cm = 5000 m

4: 200000	1: 50000
1 cm = 5000 m	1: 500000
1 cm = 50 m	1: 5000
RF = 1/50000	1: 50000

• Higher the R.F (Representative fraction) value, larger the scale.

Example: $\frac{1}{1000}$ scale is larger scale than $\frac{1}{10000}$ scale.
Note: $\text{Scale}=\frac{\text{map distance}}{\text{ground distance}}$

• There are other types of scale also.

Engineering scale: It is represented by statements.
Example 1 cm = 10 m
Graphical scale: It is a line drawn on the map so that its distance on the map corresponds to a convenient unit length on the ground.
