A rectangular garden has a 5-metre-wide road outside around all the four sides. The area of the road is 600 square metres. What is the ratio between the length and the breadth of that plot?	Choose the correct choice
A) 3 : 2 B) 4 : 3 C) 5 : 4 D) Data inadequate E) None of these
Area of shaded portion = 600 m.   ∴ (l + 10)(b + 10) – lb = 600   or, lb + 10b + 10l + 100 – lb = 600   or, 10 (b + (l) = 500   ∴ b + l = 50   From this equation we can’t get the required ratio   Answer Data inadequate
