Two employees X and Y are paid a total of Rs. 650 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?
Pick one:
A) s . 200.45
B) s . 250.45
C) s . 295.45
D) s . 300.45
E) s . 310.45

Rationale: "let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 650 but x = 120 % of y = 120 y / 100 = 12 y / 10 ∴ 12 y / 10 + y = 650 ⇒ y [ 12 / 10 + 1 ] = 650 ⇒ 22 y / 10 = 650 ⇒ 22 y = 6500 ⇒ y = 6500 / 22 = rs . 295.45 c )"
Answer: C
