BPSC TRE 1 PYQ Quiz – GS Paper for Primary Teacher 1st Shift

Short Explanation: Simplify the square root. sqrt(196/169)=14/13 So, $=1+x/13$, which solves to x=1.

Explanation: The volume of the metal is conserved. Volume of Sphere = Volume of Cylinder (wire). Solving (4/3)π(3)³ = π(0.2)²h for height (h) gives 900 cm, which is 9 m.

Explanation: Let SP be the selling price of one chair. Loss = 6SP. CP of 30 chairs = 30SP + 6SP = 36SP. Loss % = (6SP / 36SP) × 100 = 16²/₃%.

Explanation: Let the number be 10x+y. So, xy=36 and 10x+y – 45 = 10y+x. Solving gives 9x – 9y = 45 → x – y = 5. The pair that satisfies x-y=5 and xy=36 is (9,4). The number is 94, which is not in options (A), (B), or (C).

Explanation: Given a+b+c=0, then a³+b³+c³ = 3abc. The expression (a³ + b³ + c³)/abc simplifies to 3abc/abc = 3.

Explanation: Let 4ˣ = y. The equation becomes 4y + 4/y = 10. Solving gives 4y² – 10y + 4 = 0, with roots y=2 and y=¹/₂. Thus, 4ˣ=2 gives x=¹/₂ and 4ˣ=¹/₂ gives x=-¹/₂. So, both A and B are correct.

Explanation: Using the division algorithm: Dividend = (Divisor × Quotient) + Remainder. So, x³ – 3ײ + x + 2 = g(x)(x² – x + 1) + (-2x + 4). Solving for g(x) gives g(x) = (x³ – 3ײ + 3× – 2) / (x² – x + 1) = x – 2.

Explanation: Radius = 7/2 = 3.5 cm. Height of cone = 14.5 – 3.5 = 11 cm. Volume = Volume of Hemisphere + Volume of Cone = (²/₃)πr³ + (¹/₃)πr²h. Substituting values and π = 22/7 gives 231 cm³.

Using the principle of inclusion-exclusion: Total = n(Rummy) + n(Tambola) – n(Both) = 320 + 350 – 220 = 450.

Explanation: Let present age be x. So, 1/(x-2) + 1/(x+2) = 2/3. Solving this equation: 2x/(x² – 4) = 2/3 → 3x = x² – 4 → x² – 3x – 4 = 0. The positive root is x = 7.

Explanation: For a unique solution, the ratio of coefficients should not be equal: 1/3 ≠ -k/2. This gives k ≠ -²/₃. So k can be any value except -²/₃. None of the given options exclusively satisfy this condition.

Explanation: Area of sector = (θ/360) × πr². Substituting values: 102.7 = (θ/360) × (²²/₇) × 14². Solving gives θ ≈ 60°.

Explanation: Quarterly rate = 16%/4 = 4%. Period = 9 months = 3 quarters. Amount = 15625 × (1 + 4/100)³ = 17576. CI = 17576 – 15625 = ₹1,951.

Explanation: For a quadratic equation ax²+bx+c=0, product of roots = c/a. Here, product = (k+8)/(3k) = 3. Solving: k+8 = 9k → 8 = 8k → k=1.

Explanation: log_√₂(32) = log_{2^½}(2⁵) = 5 / (¹/₂) = 10.

Explanation: Let base = x, altitude = x-6. Using Pythagoras: x² + (x-6)² = 218. Solving: 2x² – 12x + 36 = 218 → x² – 6x – 91 = 0. Solving gives x=13 (base) and altitude=7.

Electric potential (more correctly, potential difference) is the amount of work done in moving a unit charge between two points.
The device used to measure this potential difference in a circuit is the voltmeter.

Magnetic field is a vector quantity because it has both magnitude and a definite direction.

A man’s weight remains the same in sitting, standing, or lying positions because weight depends only on mass and gravity, not posture.

Violet light refracts the most in a prism because it has the shortest wavelength and bends the maximum.

Ice is denser than kerosene, so it sinks and displaces more volume than the water it becomes after melting, causing the oil level to fall.

 Let the letter’s alphabetical position be n. The mapping is
A → 1 because 1=1 \sqrt{1}=11​=1 (A is 1st letter),
D → 2 because 4=2 \sqrt{4}=24​=2 (D is 4th letter),
P → 4 because 16=4 \sqrt{16}=416​=4 (P is 16th letter).

So the rule is value=alphabet position \text{value} = \sqrt{\text{alphabet position}}value=alphabet position​.
We need value $=3$ ⇒ alphabet position =32=9=3^2=9=32=9 ⇒ 9th letter is I.
