Two employees A and B are paid a total of Rs. 550 per week by their employer. If A is paid 150 percent of the sum paid to B, how much is B paid per week?
Choose the correct choice from the following choices
A) 130	B) 140	C) 150	D) 220	E) 280

Rationale: let the amount paid to a per week = x and the amount paid to b per week = y then x + y = 550 but x = 150 % of y = 150 y / 100 = 15 y / 10 ∴ 15 y / 10 + y = 550 ⇒ y [ 15 / 10 + 1 ] = 550 ⇒ 25 y / 10 = 550 ⇒ 25 y = 5500 ⇒ y = 5500 / 25 = rs . 220 d )
Answer: D
