Recent estimates predict that between 1982 and 1995 the greatest increase in the number of people employed will be in the category of low-paying service occupations. This category, however, will not increase its share of total employment, whereas the category of high-paying service occupations will increase its share.

If the estimates above are accurate, which of the following conclusions can be drawn?

(A) In 1982 more people were working in low-paying service occupations than were working in high-paying service occupations.
(B) In 1995 more people will be working in high-paying service occupations than will be working in low-paying service occupations.
(C) Nonservice occupations will account for the same share of total employment in 1995 as in 1982.
(D) Many of the people who were working in low-paying service occupations in 1982 will be working in high-paying service occupations by 1995.
(E) The rate of growth for low-paying service occupations will be greater than the overall rate of employment growth between 1982 and 1995.

(A) In 1982 more people were working in low-paying service occupations than were working in high-paying service occupations.

suppose, number of workers in '82:
low paying = 400
high paying = 100
total = 500

share in '82:
low paying, % = 80%
high paying, % = 20%

increase in number of workers from '82 to '95low paying = 350
high paying = 150

number of workers in '95:
low paying = 750
high paying = 250
total = 1000

share in '95:
low paying, % = 75%
high paying, % = 25%

Himalaya's strategy is perfect, just check the answers one by one and just make some calculations
