Length of a rectangular plot is 60 mtr more than its breadth. If the cost of fencing the plot at 26.50 per meter is Rs. 5300, what is the length of the plot in mtr?
Choose the correct choice from the following answers:
A) 46 m	B) 60 m	C) 58 m	D) 78 m	E) 80 m

Rationale: "let breadth = x metres . then , length = ( x + 60 ) metres . perimeter = 5300 / 26.5 m = 200 m . 2 [ ( x + 60 ) + x ] = 200 2 x + 60 = 100 2 x = 40 x = 20 . hence , length = x + 60 = 80 m e"
Answer: E
