Two employees A and B are paid a total of Rs. 570 per week by their employer. If A is paid 150 percent of the sum paid to B, how much is B paid per week? Pick one:
A) s . 130	B) s . 140	C) s . 150	D) s . 228	E) s . 282

Rationale: "let the amount paid to a per week = x and the amount paid to b per week = y then x + y = 570 but x = 150 % of y = 150 y / 100 = 15 y / 10 ∴ 15 y / 10 + y = 570 ⇒ y [ 15 / 10 + 1 ] = 570 ⇒ 25 y / 10 = 570 ⇒ 25 y = 5700 ⇒ y = 5700 / 25 = rs . 228 d )"
Answer: D
