#### gmatprep IR question

Fri May 25, 2012 8:44 pm
can anyone please tell me how to solve these kind of IR questions?

The graph shows the effect of voters previously stated preference regarding the issue of working time reduction on the probability of those voters actual choice being the same as the stated preference.

Hi tuhina,

In IR questions that includes tables, charts or graphs, it's important to understand what the data "means." Based on the chart and the description next to it, here's what you should notice:

1) There are 5 political parties (including "no preference") and each has a line on the graph.
2) The lines represent the probability that a party members vote the SAME as their preference.
3) Preferences vary from "against" to "for" with 3 options "in the middle"
4) Individual data points will tell you the probability that one's "vote" matches one's "preference." For example, in the Delta party, if you look at the point that is farthest to the right, it tells you that about 80% of the Delta members whose preference is "for" the issue actually vote "for" the issue (and by deduction, about 20% vote in a way that differs from their preference).

The drop-down questions that follow ask you to look for "trending" data in the chart.

Q1 The party that is MOST apt to vote according to the preference (e.g. how they vote matches what they prefer). We'd be looking for an overall line that has a high percentage. Overall, the Delta line is above the other lines (except for one spot). THAT line is most apt to vote according to its preference.

Q2 The part that is MOST apt to vote AGAINST the policy IF the presence is to vote AGAINST. Here, we're looking for a specific point that has a high percent for the AGAINST option. The highest point is on the Zeta line

GMAT assassins aren't born, they're made,
Rich
