Question

Rahul was inspecting a "blueprint” of a building that was about to be constructed. A blueprint is like a miniature model of the building. He noticed a small indication at the top corner saying "Scale 1:1000”. What is the significance of this?

• A. 1 cm is equivalent to 1000 cm
• B. 1 cm is equivalent to 100 m
• C. 1 unit is equivalent to 1000 units
• D. None of these

Answer 1

The correct option is C 1 unit is equivalent to 1000 units

Here, 1:1000 means that every 1 unit in the blueprint is equivalent to 1000 units of actual size of the building.
Since this unit is not specified in the question, we cannot assume it to be cm or m or km.

For example, if the unit is in cm and the building height is 10 cm in the blueprint, then the actual height of the building would be 1000 x 10 cm = 10,000 cm or 100 m (since 1 m = 100 cm).
