Two employees X and Y are paid a total of Rs. 572 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?
Choices
A) s . 250	B) s . 280	C) s . 290	D) s . 260	E) s . 300

Rationale: "let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 572 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 572 ⇒ y [ 12 / 10 + 1 ] = 572 ⇒ 22 y / 10 = 572 ⇒ 22 y = 5720 ⇒ y = 5720 / 22 = 520 / 2 = rs . 260 d"
Answer: D
