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....
