Graphics Interpretation one of types of questions that will appear on the\u00a0new Integrated Reasoning section<\/a>!<\/p>\n

The following two graphs show economic data from 2005.<\/p>\n

The real Integrated Reasoning Questions will have drop-down menus for the answer choices.\u00a0 For now, we are giving the equivalent form of standard multiple-choice, like ordinary GMAT Problem-Solving Questions.<\/p>\n

 <\/p>\n

1) The ratio of the US's 2005 GDP to Japan's 2005 GDP is closest to:<\/p>\n

A) 1 to 4<\/p>\n

B) 1 to 3<\/p>\n

C) 3 to 4<\/p>\n

D) 3 to 1<\/p>\n

E) 4 to 1<\/p>\n

 <\/p>\n

2) India's 2005 GDP is what percent of China's 2005 GDP is closest to<\/p>\n

A) 17%<\/p>\n

B) 47%<\/p>\n

C) 71%<\/p>\n

D) 117%<\/p>\n

E) 211%<\/p>\n

 <\/p>\n

3) In 2005, the US GDP surpassed China's GSP by approximately<\/p>\n

A) $1.25 trillion<\/p>\n

B) $3.00 trillion<\/p>\n

C) $4.50 trillion<\/p>\n

D) $7.50 trillion<\/p>\n

E) $11.25 trillion<\/p>\n

 <\/p>\n

4) India's 2005 percent growth in GDP is approximately what percent of the US's percent growth in GDP?<\/p>\n

A) 25%<\/p>\n

B) 37%<\/p>\n

C) 84%<\/p>\n

D) 152%<\/p>\n

E) 288%<\/p>\n

 <\/p>\n

Given that the percentage in the second chart is the percent by which last year's<\/span> GDP increased to arrive at this year's GDP, find the approximate dollar amount by which China's GDP increase from 2004 to 2005.<\/p>\n

A) $485 billion<\/p>\n

B) $669 billion<\/p>\n

C) $786 billion<\/p>\n

D) $962 billion<\/p>\n

E) $1.37 trillion<\/p>\n

Practice Question Answers and Explanations<\/span><\/strong><\/p>\n

(1) D<\/strong>; (2) B<\/strong>; (3) C<\/strong>; (4) E<\/strong>; (5) B<\/strong>;<\/p>\n

Notice, on these questions you are not expected to be able to read exact values off the graph.\u00a0 This is all about approximating, which is a vital skill not only on IR but also on the Quantitative Section in general.<\/p>\n

1) Looking at the chart with the blue bars, the US's bar is slightly below $12 trillion, and Japan's bar is slightly below $4 billion \u2013 approximating to $12 billion and $4billion respectively, the ratio 12\/4 = 3\/1, or 3 to 1.\u00a0 Answer = D<\/strong>.<\/p>\n

2) According to the phrasing, India is the part, and China is the whole.\u00a0 On the chart with the blue bars, China's part is close to $7 billion, and India's appears to be above $3 billion but is definitely below $4 billion.\u00a0 If we approximate India as $3.5 billion, then it's exactly half \u2013 that is, 50%.\u00a0 The only answer choice even vaguely close to 50% is 47%, answer = B<\/strong>.<\/p>\n

3) Here, we are just being asked how much longer one bar is than another. On the blue chart, the US bar is slightly below $12 trillion, maybe $11.5 trillion.\u00a0 The China bar is close to $7 billion.\u00a0 Subtracting, 11.5 \u2013 7 = 4.5, so the difference is approximately $4.5 trillion.\u00a0 Answer = C<\/strong>.<\/p>\n

4) According to the phrasing, India is the part<\/span>, and the US is the whole<\/span>.\u00a0 On the graph with the green bars, we see that India actually has a higher rate of growth than does the US, so the percent will be greater than 100%.\u00a0 The US percent of growth is approximately 3%, and India's is close to 9%, almost three times bigger, so we expect a percentage that is close to 300%.\u00a0 The only one even close is 288%.\u00a0 Answer = E<\/strong>.<\/p>\n

5) In 2005, China's GDP was approximately $7 trillion.\u00a0 According to the graph with the green bars, this was just over a 10% increase from the 2004 value.\u00a0\u00a0 Call the 2004 value x.\u00a0 To get a 10% increase, we need to change the percent to a decimal and add one to get a multiplier \u2013 0.10 is the decimal, and 1.1 is the multiplier.\u00a0 Thus, 7 = 1.1x. \u00a0Using the onscreen\u00a0calculator, we get 6.36 \u2013 so the 2004 value of China's GDP must have been around 6.36\u00a0trillion. The difference, 7 \u2013 6.36 = .64, again, with help from the onscreen calculator. That's\u00a0$0.64 trillion, or $640 billion. By far, the closest answer choice is $669 billion. Answer = B.<\/strong><\/p>\n
