For MBA aspirants, GMAT is the examination that opens the doors of the top business schools in the world. Graduate Management Admission Test or GMAT is a computer- adaptive test that is conducted worldwide for admission to the management and business courses in various international Universities. The GMAT exam pattern is of 3 hours and 30 minutes which tests the verbal and analytical skills of an individual.

Most of the top business schools across the globe accept the score of GMAT for admission to the prestigious MBA course. Scoring more than 700 in the GMAT exam can be challenging. GMAT examination is divided into 4 sections:

### GMAT Integrated Reasoning Section

The Integrated Reasoning section in GMAT is a 30 minutes long section that contains 12 questions. The section tests the real-world skills of a candidate that is required in both business schools and modern workplace. It analyses your ability to interpret and analyze information given in the form of words, charts, graphs, and tables. To score well in the Integrated reasoning section, let us discuss one of the parts today.

There are four integrated reasoning type questions:

• Two-part Analysis
• Multi-source Reasoning
• Graphic Interpretation
• Table Analysis

The GMAT Integrated Reasoning section is all about data. You’ll sort through a large amount of information, pick out significant details, and use a combination of math and verbal skills.

### Two-Part Analysis Questions

The most popular type is Two-part analysis of GMAT in Integrated Reasoning. There will be 4 out of the 12 integrated reasoning questions given in this format. GMAT two-part analysis questions are given in the form of a short written explanation of a situation or math problem which is presented in the form of two questions that relate to the same information.

GMAT Two- part analysis can be either quant or verbal oriented. A candidate will be given two columns, which means, two parts questions will be asked to make a choice that corresponds with each of the two columns. Some two-part combinations include: Yes/No, True/False, Assumption/Conclusion, Positive/Negative, Prime/Non-Prime, or any other kind of custom-created column combination.

### GMAT Two Part Analysis Questions And Solutions

#### Question 1

Set 1: Red, Blue, Yellow

Set 2: Pink, Turquoise, Orange

Set 3: Purple, Green, Brown

Set 4: Black, White, Silver

A certain company is launching three new products. Color schemes for the packaging are to be selected from colors in the four sets above. Four different colors are needed for each product. For each color scheme, not more than two colors can be selected from one set, and colors from not more than three sets can be used.

The first three colors selected for each of the products are

Product 1Product 2Product 3
YellowBlueGreen
PinkWhiteSilver
SilverRedTurquoise

Select a color that could be used for the fourth color for all three products. Select a color that could not be used as the fourth color for any of the products.

Could not be usedCould be used
Orange
White
Yellow
Purple
Green
Brown

SOLUTION AND EXPLANATION 1:

Since for product 1, the color cannot be purple, green or brown or yellow, for product 2 it cannot be yellow or white as it already used white and for product 3, it cannot be red, blue or yellow. So, the fourth color for all the three products is Orange. After analyzing all these statements, it is clear that the color which is not suitable to complete any of the color schemes is Yellow.

#### Question 2

A taxi service charges a base fare of \$5 and a rate of \$M per mile for the first 10 miles. Thereafter the rate is \$0.5M per mile. There is also a charge of \$3 per suitcase. Students traveling from and to the local college get a twenty percent discount on the mileage rates. A is a teacher traveling a distance of 8 miles with one suitcase. B is a student traveling 30 miles with two suitcases from the college to the station.

Select the expression for the difference between the amounts paid by A and B in dollars, and for the amount paid by A in dollars.

DifferenceAmount paid by A
8 (1 + M)
3 + 8M
3 + 16M
11 + 16M
3 (1 + 8M)
8M

SOLUTION AND EXPLANATION 2:

A has to pay 5+8M+3 which is equivalent to 8+8M which can also be written as 8(1+M). Also, B has to pay 5+0.8(10M+0.5M*20) which is equivalent to 11+0.8(20M) or it can be written as 11+16M.

The difference in their amount is 11+16M / 8+8M which is equivalent to 11+16M / 8-8M = 3+8M.

#### Question 3

On planet K, there is essentially no atmosphere, so objects in freefall experience no air friction. At time t = 0, an object released from rest accelerates downward at a uniform rate: it’s downward speed uniformly increases. At time t = 2 seconds, the object has fallen a distance D in meters from its original height. At time t = 5 seconds, the object is 75 meters below its original height, and is moving at a downward speed of v in meters per second.

1. the table below, select values of D, the distance below the initial height at t = 2 seconds, and v, the downward speed at t = 5 seconds, that are consistent with the information provided. Make only two selections, one in each column.
DV
12
30
60
75
90
150

SOLUTION AND EXPLANATION:

As it can be observed from the question that the object has fallen 75 meters in 5 seconds, that accounts for the average being 15 meters per second. The initial speed is 0. This means that the average speed for the entire five seconds becomes:

Initial speed+Final speed2

0+Final speed2 = 15

Final Speed= 30.

This is the speed at time t= 5 seconds. Now, it is given that the object is increasing speed at a uniform rate from 0 to 30 seconds, so at t= 2 seconds, the speed is 12.

So, the average speed over first two seconds is given as:

Initial speed+Final speed2

If the object moved downward at an average speed of 6 meters/second for 2 seconds, then it covers 12 meters.

v = 30

D = 12

#### Question 4

P, from Design Solutions, costs \$60 per chair. Chair Q, from Seat Unlimited, costs \$90 per chair. An office manager often has to buy several chairs to stock the floor space of new offices. On one occasion, she orders p of chair P, and q of chair Q. The average cost of a chair would be

Average = (60p+ 90q )(p+q)

In the table, select a value for p and value for q corresponding to an average cost per chair of \$70. Make only two selections, one in each column.

PQNumber of Chairs
--21
--28
--36
--45
--56
--63

SOLUTION AND EXPLANATION:

Here, it is given that the average is \$70, so it means

Average = (60p+ 90q )(p+q)

70= (60p+ 90q )(p+q)

70(p + q) = 60p + 90q

70p + 70q = 60p + 90q

10p + 70q = 90q

10p = 20q

p = 2q

This gives the relationship between p and q. The only numbers that satisfy this relationship are p= 56 and q= 28.

#### Question 5

Commissioner: at the present time, the forty-mile stretch of interstate highway from the town of Hillsborough to the city of West Fredericksport is clogged every weekday with a commuter who lives in Hillsborough and work in West Fredericksport. Our department is considering increasing the lanes in this stretch of the interstate highway, and the town of Hillsborough could benefit its citizens by contributing to this highway improvement.

Mayor of Hillsborough: we could contribute much more to the well-being of citizens of Hillsborough by investing that same money in a stimulus package to increase the number of jobs here in Hillsborough.

Suppose that the highway commissioner’s and mayor’s statements express their genuine opinions. Select statements (1) and (2) as follows: the highway commissioner would likely disagree with (1), and the mayor would take (2) to present logical support for (1). Select only two statement, one per column.

SOLUTION AND EXPLANATION:

Here, first, consider Choice A. According to this option, the highway commission would disagree with this but it is not clear if a mayor would agree or not. The fact is that even if expanding the highway is not a good option, that doesn’t mean it is harmful too.

Option B. Also, The mayor would agree with this but it is not clear in the case of the higher commissioner. Nothing in what the highway commissioner says gives any clear indication that he would disagree with this.

Choice C is not at all relevant. It is not at all clear if the speaker would agree or not. The same is in the case of Option D.

Choice E somehow opposes the highway commissioner’s argument but paraphrases that of the mayor. Hence, it is clear that the commissioner would disagree and the mayor would support this. This is a good candidate for Statement (1).

Choice F is not directly relevant. Here, it is clear that the highway commissioner might agree but it is not at all clear in the case of mayor if he would agree or disagree.

Statement (1) = (E)

Statement (2) = (B)

#### Question 6

Among the teachers at Ashcroft High School, English and History teachers have the heaviest grading burden. In addition to the smaller daily assignments that all other teachers must grade, English and History teachers, especially of junior and senior students, must grade lengthy writing assignments a few times a semester — literary essays in English and term papers in History. Therefore, since English and History teachers grade more, they should be paid more than the teachers of other subjects.

Select Strengthen for the statement that would, if true, most strengthen the argument, and select Weaken for the statement that would if true, most weaken the argument. Make only two selections, one in each column.

SOLUTION AND EXPLANATION:

Let us examine each option individually.

• Choice A is irrelevant because the question is based on time spent grading the students, so time spent meeting with students doesn’t hold any significance.
• Coming on choice B, it is irrelevant too. Because there is no indication regarding teaching different grade levels that would involve more or less time spent grading papers.
• Choice C is vague because that makes an appeal to what most schools do. All the schools do things differently, some give equal pay to teachers of all subjects while others do things differently. So, we cannot come to any conclusion.
• Choice D is out of flaw here. Because science teacher spends time grading lab reports too while English and History teachers don’t do that. So, giving equal pay is not considered equal and fair. This is a weakener.
• Choice E is irrelevant. It doesn’t matter who implements the decision of the pay system. It sounds as if the union is interested in basing pay on “merit”, which is a different criterion than the one supported in the argument.
• F is considered as a strengthener. Because if this is true, then indeed, pay reflects hours of work, and so if the English and History teachers do work many more hours because of all the grading they have, then they would get paid accordingly.

• Weakener- Option D
• Strengthener- Option F

#### Question 7

A contractor is hired to construct two concrete retaining walls for the city: Harrison Wall and Jackson Wall. As part of his budget, he needs to calculate the cost of the concrete he will use. For raw materials for the concrete, he has to pay \$9.75 per cubic meter of concrete. Harrison Wall will be 35 cm thick and will have dimensions of 11.5 m long and 8.1 m high. Jackson Wall will be 50 cm thick and will have dimensions of 31.0 meters long 11.8 m high.

In the table, select the value that the closest to the cost of the concrete for Harrison Wall as well as the cost of the concrete for Jackson Wall. Make only two selections, one in each column.

SOLUTION AND EXPLANATION:

The question is based on the estimation theory.

Here, the cost of concrete is \$10 per cubic meter of concrete

So, that means Harrison Wall= Also, the cost of Harrison= \$320

Now, Jackson Wall cost of Jackson = \$1800

Hence, the answers are as calculated above.

#### Question 8

Better Home Mortgage has 1200 realtors on staff, while Dream Lenders has 2400. Each year, the number of realtors is increasing by a fixed amount. A housing market specialist suggests that if each organization keeps its current rate of increase, they will have the same number of realtors on staff after three years and that subsequently, Better Home Mortgage will have more realtors.

Identify the number of increased realtors per year for Better Home Mortgage and for Dream Lenders that are consistent with the specialist’s prediction. Make only one selection in each column.

Better Home Mortgage Dream Lenders

• 10
• 40
• 110
• 240
• 410
• 620

SOLUTION AND EXPLANATION:

The new equation after having an equal number of realtors after three years becomes:

• 1200 + 3x = 2400 + 3y
• 3x = 1200 + 3y
• x = 400 + y

Better Home mortgages start with half as many relators, but in the course of a time period of three years, it overtakes Dream Lenders. So, that means Better Home Mortgage must have a higher rate of realtors. It means that the answer is 410 and 10.

#### Question 9

Identify the number of lenders less than Better Home Mortgage Dream Lenders is adding to its organization annually if the specialist was mistaken and the number of realtors would be equal after just two years. Also, identify the number of lenders Better Home Mortgage will have after two years if they add 115% of that difference annually.

Dream Lender Better Home Mortgage

• 600
• 630
• 650
• 660
• 670
• 690

SOLUTION AND EXPLANATION:

The new equation according to the question given becomes:

• 1200 + 2x = 2400 + 2y
• 600 + x = 1200 + y
• x = 600 + y

This means that for each year, Better Home Mortgage adds 600 more realtors than Dream Landers. It otherwise means that dream lander is adding 600 less mortgages every year. That means Better Home Mortgage will add 5% of “that difference” annually, or 600. 115% of 600 = 1.15(600) = 690. Hence, the answers are 600 and 690.

#### Question 10

A set of expressions consists of a total of four expressions: these three expressions {2n+8, n+4, 6n–2}, and one additional expression. From the following expressions, select the one that could be the fourth expression in the set and the one that could be the resulting arithmetic mean of the four expressions in the set. Make only one selection per column.

SOLUTION AND EXPLANATION:

In order to solve this question, we will evaluate all the three expressions given in the question. All three expressions that are provided are one digit values multiplied by n and then added to some other one-digit value or a digit value is subtracted from it. So, the similar expressions in the choice of answers given are expressions B, C, and F.
