  • question_answer
    The cost of levelling a rectangular ground at Rs.1.25 per \[{{m}^{2}}\]is Rs.900. If the length of the ground is 30 m, then the width is

    A)  6 m                            

    B)  18m    

    C)  24 m                          

    D)  36 m

    Correct Answer: C

    Solution :

    Area of ground \[=\frac{Total\text{ }cost\text{ }of\text{ }levelling}{Rate}\] \[=\left( \frac{900}{125} \right)=720{{m}^{2}}\] \[\therefore \]  Breadth of ground \[=\frac{Area\text{ }of\text{ }ground}{Length\text{ }of\text{ }ground~~}=\frac{720}{30}=24\,m\]
