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.

Hi,
Let's say there are 40 low-paying service occupations and 20 high-paying service occupations in 1982 out of 100 occupations.
Let the number of occupations be 200 in 1995.
So, Number of low-paying -> 80(same share, but absolute increase is 40)
Number of high-paying -> 50 (share increased from 20 to 25%, but absolute increase is 30)

Consider this example, B will be wrong
E should be wrong because, if the share of low-paying service remains same, the rate of increase of both should be same.

Hence, A
Cheers!

Correct option is A. You can do this through process of elimination by applying examples to each option. The example for option A is as follows:

Hope this helps.

@Frankenstein
Let's say there are 40 low-paying service occupations and 20 high-paying service occupations in 1982 out of 100 occupations.
Your explanation starts with the above quote / assumption which is same what Op A suggests, means u are actually assuming Op A and then put an explanation, sorry i didn't understand your approach here, instead of arriving on correct answer you are actually assuming an Op as an answer and then putting an explanation, m bit confused with your approach here.

@Taurus Online

i appreciate your effort but i think your table has errors, see the question state that share of low paying job remains same means

total low paying jobs in 1982 / total jobs in 1982 *100 = ttl low pay. jobs in 1995 / ttl jobs in 1995 * 100

but ur table suggests

60 / 100 * 100 = 100 / 175 * 100 ------------> wrong

please justify???

Firstly,
There is no assumption. It is a counter example to eliminate the contenders. If you are still not convinced and believe this is an assumption, you can try to find a counter example to disprove A, and which concurs with another option.

There is no mistake in this. Question stem says, "This category, however, will not increase its share of total employment". This doesn't mean it has to be same. It can even decrease.
Btw, What is the OA?
Cheers!

YEAR LOW_PAYING HIGH_PAYING NON-SERVICE TOTAL
---- ---------- ----------- ----------- ------
1982 5 85 10 100
1995 10 150 40 200

All the options other than B are proved false with this example.
Hence OA : B

Let me know if you find any issues in my answer.

Hi,
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
But, in your example, increase in low-paying jobs is 5 (10-5), where as the increase in high-paying jobs is 65. Hence, this example cannot be used.
Cheers!

Working with numbers is great, but it takes long time by trying out all possible combinations. But if you pay attention to the premesis closely:

The category of high-paying service occupation will increase its share, resulting in either 10 to 20% or 80 to 90%. Therefore, predictin in terms of number (more people will be working in high-paying service occupations) will be wrong. So, B is out.

First of all, we do not know whether overall employment takes into account only the low-paying and high-paying service occupations. Even if we assume that, we can not compare without having actual rate of increase in solid numbers or percents for high-paying service occupations. So, E is out.

There is no word about Nonservice occupations. So, C is out.

Perdiction is well beyond the given information. So, D is out.

By process of elimation, answer comes down to A.

By the way, what is the source for this question?
