(A)	$X^{C} X^{c}$	$X^{c} Y$
(B)	$X^{c} X^{c}$	$X^{c} Y$
(C)	$X^{C} X^{C}$	$X^{C} Y$
(D)	$X^{C} X^{c}$	$X^{C} Y$

Field $X$ and $Y$ are to be enclosed with a fencing at the cost of $R s . 40$ per meter. If the cost on field $X$ is denoted by $C_{x}$ and that on field $Y$ is denoted by $C_{y}$ , we have

$C_{x} = C_{y}$ ,
$C_{x} < C_{y}$ ,
$C_{x} > C_{y}$ ,
cannot be determined

The correct option is A $C_{x} = C_{y}$ ,
Perimeter of field $X$
$= 470 + 290 + (470 - 180) + 180 + (470 - 290) + 470 = 4 \times 470 = 1880 m .$
Perimeter of field Y $= 4 \times 470 = 1880 m$ .
Hence, $C_{x} = 1880 \times 40$ and $C_{y} = 1880 \times 40$
$\Rightarrow C_{x} = C_{y}$

Field X and Y are to be enclosed with a fencing at the cost of Rs.40 per meter. If the cost on field X is denoted by Cx and that on field Y is denoted by Cy, we haveCx=Cy,Cx<Cy,Cx>Cy,cannot be determined

The correct option is A Cx=Cy,Perimeter of field X=470+290+(470−180)+180+(470−290)+470=4×470=1880m.Perimeter of field Y =4×470=1880m.Hence, Cx=1880×40 and Cy=1880×40⇒Cx=Cy

Field $X$ and $Y$ are to be enclosed with a fencing at the cost of $R s . 40$ per meter. If the cost on field $X$ is denoted by $C_{x}$ and that on field $Y$ is denoted by $C_{y}$ , we have

$C_{x} = C_{y}$ ,
