Question

The cost of flooring a room at ₹68 per square meter is ₹2040. If the length of the room is 7.5 m, what is the breadth?

पर्याय

• 3 m

• 4 m

• 5 m

• 6 m

Answer 1

4 m

Explanation:

Area = Total cost ÷ Rate = 2040 ÷ 68 = 30 m².

Using Area = length × breadth, we get 30 = 7.5 × breadth,

[ `30/7.5` ​= `"30 × 10" /"7.5 × 10"`​ = `300/75` ]​

so breadth = 4 m.
