Two employees X and Y are paid a total of Rs. 506 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 the most appropriate option
A) s . 250  B) s . 280  C) s . 290  D) s . 299  E) s . 230

Rationale: "let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 506 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 506 ⇒ y [ 12 / 10 + 1 ] = 506 ⇒ 22 y / 10 = 506 ⇒ 22 y = 5060 ⇒ y = 5060 / 22 = 460 / 2 = rs . 230 e"
Answer: E
