A) 5.7 cm
B) 7.5 m
C) 6.7 cm
D) 7.6 cm
Correct Answer: B
Solution :
Total cost of flooring = Rs. 510 Rate of flooring = Rs. 8.50 per sq. m Area of the floor \[\text{=}\left( \frac{\text{total cost}}{\text{rate per sq}\text{. m}} \right)=\left( \frac{510}{8.50} \right)\text{sq}\text{.m}\] \[\text{=}\left( \frac{\text{510 }\!\!\times\!\!\text{ 100}}{\text{850}} \right)\text{ sq}\text{.m = 60 sq}\text{.m}\] Now, area = 60 sq. m and length = 8 m Hence, breadth \[\text{=}\left( \frac{\text{area}}{\text{length}} \right)=\left( \frac{60}{8} \right)=7.5m\]
