Two employees X and Y are paid a total of Rs. 700 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?	Select:	A) s . 200.18	B) s . 240.18	C) s . 290.18	D) s . 300.18	E) s . 318.18

Rationale: "let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 700 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 700 ⇒ y [ 12 / 10 + 1 ] = 700 ⇒ 22 y / 10 = 700 ⇒ 22 y = 7000 ⇒ y = 7000 / 22 = rs . 318.18 e )"
Answer: E
