Question

A rectangular park is 200 m by 150 m. Two cross paths are to be made one parallel to the length and the other parallel to the breadth. The longer path is to be 3 m wide and the shorter is to be 2 m wide. The cost of grassing the remaining part of the park @ Rs 1000 per hectare is

• A. Rs $2916$
• B. Rs $2910.6$
• C. Rs $2915$
• D. Rs $2900.50$

Answer 1

Answer: (B)

Rs $2910.6$

Area of cross paths$=(200\times 3+150\times 2-3\times 2)m^2$
$=894m^2$
Area of remaining part$=(200\times 200\times 150-894)m^2$
$2.9106hectare$
$Cost=Rs1000\times 2.9106=Rs2910.60$
