Q1.
Find the number of triangles in the given figure.
Answer : Option B
Explaination / Solution:
The figure may be labelled as shown.
The simplest triangles are BFG, CGH, EFM, FMG, GMN, GHN, HNI, LMK, MNK and KNJ i.e. 10 in number.
The triangles composed of three components each are FAK and HKD i.e. 2 in number.
The triangles composed of four components each are BEN, CMI, GLJ and FHK i.e. 4 in number.
The triangles composed of eight components each are BAJ and OLD i.e. 2 in number.
Thus, there are 10 + 2 + 4 + 2 = 18 triangles in the given figure.
Q2.
Directions :Questions in the form of inference/conclusions are based on the passages given below. Each passage is followed by five inferences. You are required to examine each inference separately in the context of the passage and decide upon its degree of truth or falsity.
Passage:
There is no disputing the fact that one part of globalization is the information revolution. But like all revolutions, this one has its winners and losers. Even on the Pacific Rim, home of so many economic “miracles”, the vast majority of people live on less than two dollars a day. That is what nearly half the world’s population subsists on, while the poorest 1.2 billion get by on less than one dollar. In the face of these grim realities, talk of a global information age takes on a perverse, ‘let them eat cake’ quality. What possible benefit could this “other half” derive from expanded web-based technology?
The notion that the internet will mainstream the world’s underprivileged fits a pattern of technological fantasy that reaches back at least to the mid-nineteenth century. A more immediate effect, unfortunately, has been an expanding communications gap between the rich and poor. With 90% of internet traffic in English, and native language skills eroding among non-Western internet addicts, 95% of the world’s Web users reside in developed countries. Only 0.08% of Latin Americans had Web access in 1999, which is double that of South Asia. In so far as rapid information flow translates into power, this great divide is integral to the knowledge-based and culturally driven geopolitics that Joseph S. Nye terms “soft power”.
During the mid-nineteenth century, there was a notion that the internet would make the world's poor become part of the mainstream.
Answer : Option D
Explaination / Solution:
(The first sentence talks about a "pattern of technological fantasy"; that there was an actual notion might not be true, and is most probably false, given the timeline being spoken of here.)
Q3. In how many ways can four children be made to stand in a line such that two of them, A and B are always together?
Answer : Option B
Explaination / Solution:
No Explaination.
Q4.
Directions: Study the following information and answer the questions.
Eight friends A,B,C,D,E,F,G and H are sitting around a circular table. Some are facing the centre while some are not facing the centre(ie in a direction opposite the centre).
G is not facing the centre. The immediate neighbors of H face opposite directions. E sits second to the right of F, who sits on the immediate left of A. Immediate neighbors of C face the same direction. A faces inside the circle and sits third to the left D. Only one person sits between D and H and that person is neither C nor G. E is not the immediate neighbor of C but both are facing opposite directions. B faces the same direction as F. B sits second to the right of C, who is on the immediate left of F. D sits second to the left of H.
How many persons are not facing the centre?
Answer : Option A
Explaination / Solution:
Two person are not facing the centre - C & G
F sits on the immediate left of A. A faces inside the circle. E sits second to the right of F.
There will be two possibilities. F is either facing inside or facing outside. When F is facing outside.
Case 1: When F is facing outside.
A sits third to the left D. D sits second to the left of H. C on the immediate left of F. But it is given that E is not the immediate neighbor of C.Hence Case 1 is not valid.
Case2 F is facing inside.
A sits third to the left D. D sits second to the left of H. C on the immediate left of F. E is not the immediate neighbor of C. B sits second to the right of C. B faces the same direction as F.D sits second to the left of H. E and C both are facing opposite directions. Immediate neighbors of C face the same direction. Hence the required figure is.
Two person are not facing the centre - C & G
Q5.
Find the number of triangles in the given figure.
Answer : Option C
Explaination / Solution:
The figure may be labelled as shown.
The simplest triangles are AEI, AIH, BEJ, BJF, CFK, CKG, DGL, DLH, EOJ, FOJ, FOG, LOG, HOL and HOE i.e. 14 in number.
The triangles composed of two components each are EAH, FBE, BEO, EOF, BFO, FCG, GDH, HOD, HOG and GOD i.e. 10 in number.
The triangles composed of three components each are EFH, EHG, FGH and EFG i.e. 4 in number.
Thus, there are 14 + 10 + 4 = 28 triangles in the given figure.

Perhaps due to the use of English as the predominant language over the internet, there has arisen an expanding communication gap between the rich and the poor.
Answer : Option B
Explaination / Solution:
(The second para talks of a communications gap, but it does not state English as the clear and specific reason for the same).
Q7. P, Q, R and S are four men. P is the oldest but not the poorest. R is the richest but not the oldest. Q is older than S but not than P or R. P is richer than Q but not than S. The four men can be ordered (descending) in respect of age and richness, respectively, as:
Answer : Option B
Explaination / Solution:
No Explaination.
Q8.
Directions: Study the following information and answer the questions.
Eight friends A,B,C,D,E,F,G and H are sitting around a circular table. Some are facing the centre while some are not facing the centre(ie in a direction opposite the centre).
G is not facing the centre. The immediate neighbors of H face opposite directions. E sits second to the right of F, who sits on the immediate left of A. Immediate neighbors of C face the same direction. A faces inside the circle and sits third to the left D. Only one person sits between D and H and that person is neither C nor G. E is not the immediate neighbor of C but both are facing opposite directions. B faces the same direction as F. B sits second to the right of C, who is on the immediate left of F. D sits second to the left of H.
Who among the following is on the immediate right of E?
Answer : Option B
Explaination / Solution:
G is on the immediate right of E
Q9.
Find the number of triangles in the given figure.
Answer : Option C
Explaination / Solution:
The figure may be labelled as shown.
The simplest triangles are ABG, BIG, BIC, CIH, GIH, CDH, HED, GHJ, HJE, FEJ, GFJ and AGF i.e. 12 in number.
The triangles composed of two components each are ABF, CDE, GBC, BCH, GHG, BHG, GHF, GHE, HEF and GEF i.e. 10 in number.
The triangles composed of three components each are ABH, AFH, CDG and GDE i.e. 4 in number.
The triangles composed of four components each are BHF and CGE i.e. 2 in number.
Total number of triangles in the figure = 12 + 10 + 4 + 2 = 28.

The information revolution will bring the world's poor out of the depths of their financial and social troubles, given it spreads through the masses with equity.
Answer : Option B
Explaination / Solution:
(The passage talks about inequitable distribution of the benefits of the information revolution, hence, this is a reasonable inference.)
