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 serive 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.


this is sort of math pb... :( would you help me with far easier explanation why the answer is A?

thanks Damager.

i totally understand your logic though, some is not solved..

low-paying increase
{(5,000-50)*100}/10
--> *100 means total employed persons' share, 100 employees in 1982 to 10,000 ones in 1995?
--> and then, where comes /10?

hum....
