A) 462.3
B) 362.5
C) 562.4
D) None of these
Correct Answer: B
Solution :
Area of the plot \[=(90\times 6){{m}^{2}}\] \[=5400\,{{m}^{2}}\] Area of the plot excluding the path \[=\left[ (90-5)\times (60-5) \right]\,\,{{m}^{2}}\] \[=4675\,\,{{m}^{2}}\] Area of the path \[=(5400-4675)\,{{m}^{2}}\] \[=725\,\,{{m}^{2}}\] Cost of gravelling the path \[=Rs.\,725\times (50/100)=Rs.\,362.5\]
