Two employees X and Y are paid a total of Rs. 500 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 correct choice from the following choices
A) s . 227	B) s . 287	C) s . 297	D) s . 300	E) s . 380

Rationale: "let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 500 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 500 ⇒ y [ 12 / 10 + 1 ] = 500 ⇒ 22 y / 10 = 500 ⇒ 22 y = 5000 ⇒ y = 5000 / 22 = rs . 227.77 a )"
Answer: A
