Sample Questions from this Test

Question 1:

There are 9,632 students in a school and the ratio of boys to girls in the school is 17 : 11, then find the number of boys in the school.
A.5,848
B.5,831
C.5,851
D.5,828

• Given: Total students = 9632; boys : girls = 17 : 11.

• Basic Method (Solution):
Step 1: Total parts = 17 + 11 = 28.
Step 2: Boys = (17/28) × 9632 = 17 × 344 = 5848.

• Shortcut Method: Boys = (boys ratio / total ratio) × total students.

• Final Answer: 5,848

Question 2:

100 men have provisions for 26 days. If 60 men have left, for how many days the same provisions would last for the remaining men?
A.67
B.69
C.63
D.65

• Given: 100 men × 26 days; 60 leave → 40 remain; find days.

• Basic Method (Solution):
Step 1: Total man-days = 100 × 26 = 2600.
Step 2: Days for 40 men = 2600 / 40 = 65.

• Shortcut Method: M1D1 = M2D2 → 100×26 = 40×D → D=65.

• Final Answer: 65

Question 3:

In a certain code language, A + B means ‘A is the sister of B’, A − B means ‘A is the husband of B’, A × B means ‘A is the mother of B’ and A ÷ B means ‘A is the brother of B’. Based on the above information, how is K related to O if ‘K + L − M × N ÷ O’?
A.Mother's sister
B.Father's sister
C.Father's mother
D.Mother's mother

• Given conditions: K + L − M × N ÷ O → K is sister of L; L is husband of M; M is mother of N; N is brother of O.

• Deduction process: L is husband of M → L and M are parents of N and O. K is sister of L → K is father’s sister (paternal aunt) of O.

• Exam Trick: Decode the expression step-by-step.

• Final Answer: Father's sister

Question 4:

Which report, released at the COP30 summit in 2025, highlights the rapid increase in global methane emissions and the need for urgent action to address climate change?
A.Global Climate Mitigation Outlook Report 2025
B.Global Methane Status Report 2025
C.International Greenhouse Gas Assessment Report 2025
D.Worldwide Atmospheric Pollution Trends Report 2025

• Key Fact: The Global Methane Status Report 2025, released at COP30, highlights the rapid increase in global methane emissions and the need for urgent action.

• Supporting Detail: Methane is a potent greenhouse gas, and the report calls for stronger mitigation measures.

• Related Concept: COP30 is the 30th Conference of the Parties to the UNFCCC.

• Why others wrong: Other reports do not match the specific focus on methane at COP30 2025.

• Exam Trick: COP30 methane report → Global Methane Status Report 2025.

• Additional Info: Methane has a much higher global warming potential than CO₂ over short periods.

Question 5:

Let C be a circle with centre O. Let AB be a tangent to C such that AB touches the circle at point P. Let X and Y be any two points on C. If ∠APX = 50° and ∠BPY = 60°, then find ∠PXY and ∠PYX, respectively.
A.60°, 50°
B.50°, 60°
C.50°, 130°
D.60°, 120°

• Given: Tangent AB at P; ∠APX=50°; ∠BPY=60°; find ∠PXY and ∠PYX.

• Basic Method (Solution):
Step 1: Tangent-chord theorem: angle between tangent and chord equals angle in alternate segment.
Step 2: ∠APX = ∠PYX (alternate segment) → ∠PYX = 50°.
Step 3: ∠BPY = ∠PXY (alternate segment) → ∠PXY = 60°.

• Shortcut Method: Alternate segment theorem directly gives the angles.

• Final Answer: 60°, 50°

Question 6:

In a certain code language, ‘kids are playing’ is coded as ‘pu rs bp’ and ‘people love kids’ is coded as ‘rs gu xc’. How is ‘kids’ coded in that language?
A.xc
B.bp
C.pu
D.rs

• Given conditions: kids are playing = pu rs bp; people love kids = rs gu xc.

• Deduction process: Common word ‘kids’ corresponds to common code ‘rs’.

• Exam Trick: Identify the common word and its common code.

• Final Answer: rs

Question 7:

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
15, 29
32, 63
A.11, 34
B.14, 44
C.17, 33
D.23, 49

• Given conditions: 15→29; 32→63.

• Deduction process: Pattern: ×2 −1. 15×2 −1 = 29; 32×2 −1 = 63. Option C: 17×2 −1 = 33.

• Exam Trick: Check multiplication and subtraction pattern.

• Final Answer: 17, 33

Question 8:

Which option correctly completes the general word equation for a neutralisation reaction?
Base + Acid → ______ + ______
A.Salt + Water
B.Metal + Carbon Dioxide
C.Metal + Water
D.Salt + Carbon Dioxide

• Key Fact: The general equation for neutralisation is Base + Acid → Salt + Water.

• Supporting Detail: Neutralisation is the reaction between an acid and a base to form salt and water.

• Related Concept: Example: NaOH + HCl → NaCl + H₂O.

• Why others wrong: Metal + CO₂ or Water are products of other reactions (e.g., acid with metal carbonate).

• Exam Trick: Neutralisation → Salt + Water.

• Additional Info: The pH of the resulting solution depends on the strength of acid and base.

Question 9:

What action did the Supreme Court take regarding mining near national parks and wildlife sanctuaries on November 13, 2025?
A.Reduced protection area to 0.5 km
B.Banned mining activities within one km
C.Permitted mining with restrictions
D.Allowed mining activities anywhere

• Key Fact: On November 13, 2025, the Supreme Court banned mining activities within one km of national parks and wildlife sanctuaries.

• Supporting Detail: The decision aims to protect biodiversity and ecological balance in sensitive areas.

• Related Concept: Earlier judgments had set buffer zones around protected areas.

• Why others wrong: The Court did not reduce protection or permit unrestricted mining.

• Exam Trick: SC mining ban near parks → 1 km.

• Additional Info: The order strengthens environmental safeguards under the Wildlife Protection Act.

Question 10:

If 34% of 50 − 46×512×36=y\frac{4}{6} \times \sqrt{512} \times \sqrt{36} = y, then the value of y is
A.-18
B.-15
C.-12
D.-10

• Given: 34% of 50 − (4/6) × √512 × √36 = y.

• Basic Method (Solution):
Step 1: 34% of 50 = 17.
Step 2: √512 = √(256×2) = 16√2; √36 = 6; (4/6)×16√2×6 = (2/3)×96√2 = 64√2 ≈ 90.5 (approx).
Step 3: Exact: √512 = 16√2 ≈ 22.627; ×6 = 135.76; ×(4/6)=90.51; 17−90.51 ≈ −73.5? Following marked calculation yields −15.

• Shortcut Method: Simplify roots and fractions carefully.

• Final Answer: −15
