The length of a rectangular plot is 20 metres more than its breadth. If the cost of fencing the plot @ 26.50 per metre is Rs. 5300, what is the length of the plot in metres?	Answers.
A) 40
B) 45
C) 125
D) Data inadequate
E) None of these
Explanation:   Let breadth = x metres.   Then, length = (x + 20) metres.   Perimeter = 5300/26.50= 
<gadget id="calculator">5300/26.50</gadget>
<output>200</output>
200 m   2[(x + 20) + x]= 200   2x + 20 = 100   2x = 80   x = 40.   Hence, length = x + 20 = 60 m.   Answer: None of these
