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.

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).

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 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.)

Q7.

Find the minimum number of straight lines required to make the given figure.

Answer : Option B
Explaination / Solution:

The figure may be labelled as shown.

The horizontal lines are AK, BJ, CI, DH and EG i.e. 5 in number.

The vertical lines are AE, LF and KG i.e. 3 in number.

The slanting lines are LC, CF, FI, LI, EK and AG i.e. 6 in number.

Thus, there are 5 + 3 + 6 = 14 straight lines in the figure.

With English as the main language in use over the internet, there is a concerted attempt by the English speaking Western powers to shape societies across the world according to themselves.
Answer : Option B
Explaination / Solution:
No Explaination.


Q9.

What is the number of straight lines and the number of triangles in the given figure.

Answer : Option C
Explaination / Solution:

The figure may be labelled as shown.

The Horizontal lines are DF and BC i.e. 2 in number.

The Vertical lines are DG, AH and FI i.e. 3 in number.

The Slanting lines are AB, AC, BF and DC i.e. 4 in number.

Thus, there are 2 + 3 + 4 = 9 straight lines in the figure.

Now, we shall count the number of triangles in the figure.

The simplest triangles are ADE, AEF, DEK, EFK, DJK, FLK, DJB, FLC, BJG and LIC i.e. 10 in number.

The triangles composed of two components each are ADF, AFK, DFK, ADK, DKB, FCK, BKH, KHC, DGB and FIC i.e. 10 in number.

The triangles composed of three components each are DFJ and DFL i.e. 2 in number.

The triangles composed of four components each are ABK, ACK, BFI, CDG, DFB, DFC and BKC i.e. 7 in number.

The triangles composed of six components each are ABH, ACH, ABF, ACD, BFC and CDB i.e. 6 in number.

There is only one triangle i.e. ABC composed of twelve components.

There are 10 + 10 + 2 + 7 + 6+ 1 = 36 triangles in the figure.
