Approximately what is the projected percent ' decrease in the number of Blue-Collar workers in the workforce of Country X from 1981 to 1995 ?


(A) 42%

(B) 35%

(C) 20%

(D) 17%

(E) 7%



Blue collar workers in 1981 = 28% 0f 150 million = 42 million

Blue collar workers in 1995 = 20% 0f 175 million = 35 million

Therefore % change = \(\frac{{42 - 35}}{42}\)% = 16.666% = nearly 17%
