In a certain company, a third of the workers do not have a retirement plan. 20% of the workers who do not have a retirement plan are women, and 40% of the workers who do have a retirement plan are men. If 160 of the workers of that company are men, how many of the workers are women? Choose one
A) 80
B) 95
C) 105
D) 120
E) 140

Rationale: "set up equation : x = total number of workers 160 = 0,4 * 2 / 3 * x + 0,8 * 1 / 3 * x 160 = 16 / 30 x x = 300 300 - 160 = 140 answer e"
Answer: E
