Sketch of a plot is given. Its dimensions are mentioned. Find the cost of levelling the plot at Rs.. 12 per \[{{m}^{2}}\].
A) Rs. 1,760
B) Rs. 480
C) Rs. 552
D) Rs. 912
Correct Answer:
C
Solution :
We first find area of plot EF = 14 ? 11 = 3 m Area of portion \[DEFH=6\times 3=18\,{{m}^{2}}\] BC = 8 ? 6 = 2m Area of potion \[ABCH=14\times 2\,=28\,{{m}^{2}}\] Total area of plot \[=18+28=46\,{{m}^{2}}\] Cost of levelling plot \[=46\times 12=\text{Rs}\,552\]
