Two employees X and Y are paid a total of Rs. 880 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week? Select:
A) s . 150
B) s . 200
C) s . 250
D) s . 350
E) s . 400

Rationale: "let the amount paid to x per week = x and the amount paid to y per week = y then x + y = 880 but x = 120 % of y = 120 y / 100 = 12 y / 10 â ˆ ´ 12 y / 10 + y = 880 â ‡ ’ y [ 12 / 10 + 1 ] = 880 â ‡ ’ 22 y / 10 = 880 â ‡ ’ 22 y = 8800 â ‡ ’ y = 8800 / 22 = 800 / 2 = rs . 400 e )"
