Two employees X and Y are paid a total of Rs. 800 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?  Choose one.
A) s . 200.63
B) s . 250.63
C) s . 290.63
D) s . 300.63
E) s . 363.63

Rationale: "let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 800 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 800 ⇒ y [ 12 / 10 + 1 ] = 800 ⇒ 22 y / 10 = 800 ⇒ 22 y = 8000 ⇒ y = 8000 / 22 = rs . 363.63 e )"
Answer: E
