Sample Questions from this Test

Question 1:

Seven people F, G, H, I, V, W, and X are sitting around a circular table facing the centre of the table. H sits third to the left of F. I sits second to the left of V. Only F sits between G and I. W is not an immediate neighbour of H. How many people sit between X and I when counted from the right of X?
A.Two
B.Three
C.Zero
D.One

• Deduction: Step 1: H sits third to the left of F. Step 2: F sits between G and I. Step 3: I sits second to the left of V. Step 4: W is not an immediate neighbor of H, so W sits between X and V. This places X exactly such that when counted from the right of X, there are two people (W and V) between X and I.

• Final Answer: Two

Question 2:

The population of a village was 2,90,000. It increased by 5% in the first year and increased by 30% in the second year. Its population after two years is ______.
A.3,95,850
B.3,91,500
C.3,04,500
D.3,77,000

• Basic Method: After 5% increase → 2,90,000 × 1.05 = 3,04,500. After 30% increase → 3,04,500 × 1.30 = 3,95,850.

• Shortcut / Trick: Successive percentage increase formula = x+y+xy100x + y + \frac{xy}{100}. Here, 5+30+5×30100=35+1.5=36.5%5 + 30 + \frac{5 \times 30}{100} = 35 + 1.5 = 36.5\%. Net increase = 36.5%. 2,90,000×1.365=3,95,8502,90,000 \times 1.365 = 3,95,850.

• Final Answer: 3,95,850

Question 3:

In a certain code language, ‘GLOW’ is coded as ‘4628’ and ‘WEAR’ is coded as ‘3574’. What is the code for ‘W’ in that language?
A.3
B.7
C.4
D.8

• Given: GLOW = 4628; WEAR = 3574.

• Deduction: Look for the common letter in both words. 'W' is the only common letter. In the number codes, '4' is the only common digit. Therefore, W = 4.

• Final Answer: 4

Question 4:

Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
HGH 85 FEF 74 DCD 63 BAB 52 ?
A.ZXY 40
B.ZYZ 41
C.ZZY 41
D.ZHQ 40

• Letter Pattern: First letter: H(-2)→F(-2)→D(-2)→B(-2)→Z. Middle letter is same as the first letter. Last letter: H(-2)→F(-2)→D(-2)→B(-2)→Z. Hence, letter cluster is ZYZ.

• Number Pattern: 85(-11)→74(-11)→63(-11)→52(-11)→41.

• Final Answer: ZYZ 41

Question 5:

Which of the following letter-clusters should replace # and % so that the pattern and relationship followed between the letter-cluster pair on the left side of :: is the same as that on the right side of :: ?
# : RWU :: KPN : %
A.# = TXY , % = JLM
B.# = TYX , % = KLI
C.# = SXV , % = JOM
D.# = SYW , % = KFI

• Pattern: Test options to find consistent relative shifts. If # = SXV, the shift to RWU is: S(-1)=R, X(-1)=W, V(-1)=U. Applying the exact same shift of (-1, -1, -1) to KPN yields K(-1)=J, P(-1)=O, N(-1)=M, which matches JOM.

• Final Answer: # = SXV , % = JOM

Question 6:

When a spring is compressed from its equilibrium position, its potential energy will ______.
A.remain unchanged
B.first decrease then increase
C.increase
D.decrease

• Key Fact: The elastic potential energy of a spring is given by the formula U=12kx2U = \frac{1}{2}kx^2, where kk is the spring constant and xx is the displacement.

• Supporting Detail: Since potential energy depends on the square of the displacement (x2x^2), it is always positive. Whether the spring is stretched or compressed from equilibrium, xx increases, causing potential energy to increase.

• Deep Dive: Hooke's Law states F=−kxF = -kx. The work done against this restoring force gets stored as Elastic Potential Energy.

• Final Answer: increase

Question 7:

Items such as the operating system and device drivers fall under which category of software?
A.System software
B.Utility software only
C.Entertainment software
D.Temporary programs

• Key Fact: Operating systems (like Windows, Linux) and device drivers are classified as System Software.

• Supporting Detail: System software serves as a bridge between the computer hardware and the application software. It provides the core platform and background processes necessary for the computer to run.

• Deep Dive: Application software (like MS Word or Chrome) performs specific tasks for the user, while system software runs the computer itself. Utility software (like antivirus or disk cleanup) is actually a sub-category of System Software.

• Final Answer: System software

Question 8:

Which among the following Articles of the Indian Constitution provides Municipalities with financial powers?
A.Article 243P
B.Article 243ZB
C.Article 243U
D.Article 243 X

• Key Fact: Article 243X of the Indian Constitution authorizes the State Legislature to empower Municipalities to levy, collect, and appropriate taxes, duties, tolls, and fees.

• Supporting Detail: Part IX-A of the Constitution was added by the 74th Amendment Act, 1992, granting constitutional status to urban local bodies (Municipalities).

• Deep Dive: Other important articles: 243P (Definitions), 243W (Powers, authority, and responsibilities), and 243Y (Finance Commission review).

• Final Answer: Article 243 X

Question 9:

Which of the following statements is correct about the open system of thermodynamics?
A.Exchange of energy and matter between system and surroundings.
B.No exchange of energy, but exchange of matter is possible between system and the surroundings.
C.No exchange of energy or matter between the system and the surroundings.
D.No exchange of matter, but exchange of energy is possible between system and the surroundings.

• Key Fact: In an open thermodynamic system, both mass (matter) and energy (heat/work) can flow across the system's boundary to the surroundings.

• Supporting Detail: A classic example of an open system is boiling water in an open pan, where heat enters the pan and water vapour escapes.

• Deep Dive: Closed systems allow only energy transfer (e.g., a sealed cylinder), while Isolated systems allow neither energy nor matter transfer (e.g., a perfect thermos flask).

• Final Answer: Exchange of energy and matter between system and surroundings.

Question 10:

Which constitutional article empowers the Indian Parliament to make laws regarding the acquisition and termination of Indian citizenship after the commencement of the Constitution of India?
A.Article 6
B.Article 11
C.Article 8
D.Article 5

• Key Fact: Article 11 expressly grants the Indian Parliament the absolute power to regulate the right of citizenship by law, covering acquisition, termination, and all other citizenship matters.

• Supporting Detail: The Constitution itself (Articles 5-10) only defined citizenship at the date of its commencement (Jan 26, 1950). Parliament used Article 11 to pass the Citizenship Act, 1955.

• Deep Dive: Article 5 deals with citizenship by domicile, while Articles 6 & 7 deal with migrants from and to Pakistan during partition.

• Final Answer: Article 11
