Two employees X and Y are paid a total of Rs. 570 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 answers:	A) s . 259	B) s . 289	C) s . 299	D) s . 300	E) s . 389

Rationale: let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 570 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 570 ⇒ y [ 12 / 10 + 1 ] = 570 ⇒ 22 y / 10 = 570 ⇒ 22 y = 5700 ⇒ y = 5700 / 22 = rs . 259 a )
