A rectangular grassy plot 110 m by 65 m has a gravel path 2.5 m wide all around it on the inside. Find the cost of gravelling the path at 80 paise per sq. metre.

Options

A. Rs 680
B. Rs 860
C. Rs 608
D. None

Answer

A

Explanation

Overall area of the grassy plot is `110xx65=7150` sq. meters. The area of the grassy plot after applying the gravel path is `105xx60=6300` sq. meters. Area of the gravel path is `7150-6300=850` sq. mtrs.
Hence, `850xx0.80=Rs 680`
