1. On a certain map of India the actual distance of 1450 km between two cities Delhi and Kolkata is shown as 5 cm. What scale is used to draw the map ?

A. $1 : 15 \times 10^{6}$

B. $1 : 20 \times 10^{6}$

C. $1 : 25 \times 10^{6}$

D. $1 : 29 \times 10^{6}$

Solution:

5 cm on the map represents 1450 km
∴ 1 cm on the map represents

(\frac{1450}{5})

km = 290 km
Hence, the scale is 1 cm : 290 km i.e.,

1 : 29 \times 10^{6}

[∵ 290 km = (29 \times 10^{6}) cm]
