Question

In a blueprint of a room, an architect has shown the height of the room as 33 cm. If the actual height of the room is 330 cm, then the scale used by her is

(a) 1:11 (b) 1:10 (c) 1:100 (d) 1:3

Answer 1

(b) 1: 10

From the question it is given that,

An architect has shown the height of the room as 33 cm

The actual height of the room is 330 cm

Then, the scale used by an architect is = Drawn size/actual size

= 33/330 … [divide both by 33]

= 1/10

= 1: 10
