country of Jurania

by priyankamishra11 » Sat Sep 27, 2008 8:05 pm
From 1980 to 1989, total consumption of fish in the country of Jurania increased by 4.5 percent, and total consumption of poultry products there increased by 9.0 percent. During the same period, the population of Jurania increased by 6 percent, in part due to immigration to Jurania from other countries in the region.

If the statements above are true, which of the following must also be true on the basis of them?

A.During the 1980’s in Jurania, profits of wholesale distributors of poultry products increased at a greater rate than did profits of wholesale distributors of fish.
B.For people who immigrated to Jurania during the 1980’s, fish was less likely to be a major part of their diet than was poultry.
C.In 1989 Juranians consumed twice as much poultry as fish.
D.For a significant proportion of Jurania’s population, both fish and poultry products were a regular part of their diet during the 1980’s.
E.Per capita consumption of fish in Jurania was lower in 1989 than in 1980.

IMO E.

a) Statement on Profits is not relevant to the information given in the stimulus
b) Not mentioned in stimulus
c) Absolute value of consumption of fish or poultry products is not mentioned in stimulus
d) There could be other sources of food that forms the regular part of their diet.
e) This is correct answer.
Population consumption of fish Per capita
1980 1000 100 units 0.1
1989 1060 104.5 units 0.09

Hence per capita consumption of fish is lower in 1989 than in 1980.

consumption of fish is decreasing but population is increasing

so it may be possible that per capita consumption is decreasing but no of ppl eating fish are the same.

C says no of ppl are decreasing [in proportion]
but E justifies this position

I also think E is correct.

My take is that the consumption of fish is not decreasing, but rather it is not increasing at the rate the population is increasing. Consequently the *proportion* has decreased. E states this clearly.

Do we solve such questions mathematically ?
I use this approach !

Anything else, besides just offtopic here, If I am not wrong, in a inference question its ok to extract answer from NOT ALL parts of the argument !?

For this particular question, and for some others, a mathematical approach is certainly best. There are, however, questions involving numbers and percentages that you can answer just as easily using critical reasoning as you can using numbers and math; perhaps even more easily. For example: https://www.beatthegmat.com/ditrama-popu ... 50545.html

Correct. In inference questions, sometimes the proper inference (correct answer) is correct because of only some parts of the passage.

If the statements above are true, which of the following must also be true on the basis of them?

A.During the 1980's in Jurania, profits of wholesale distributors of poultry products increased at a greater rate than did profits of wholesale distributors of fish. - The passage talks about percentages and this talks about absolute numbers. Hence, a disconnect. We only know that the their is more increase in demand from the numbers previously sold, this doesn't mean that the profit margins per product will increase. Maybe poultry has lesser margin.

B.For people who immigrated to Jurania during the 1980's, fish was less likely to be a major part of their diet than was poultry. - We only have percentages. Again this talks about absolute values. We don't know the base values of fish or poultry. Maybe fish was anyway sold more then their lesser increase in percentage might also mean greater increase in numbers.

C.In 1989 Juranians consumed twice as much poultry as fish. - Same as B.

D.For a significant proportion of Jurania's population, both fish and poultry products were a regular part of their diet during the 1980's. - We can't infer that. Maybe, the previous populations were not eating it regularly and there has been a sudden increase due to immigrants.

E.Per capita consumption of fish in Jurania was lower in 1989 than in 1980. - Correct. Can be proven with numbers.
