Q&A: practice questions with answers

Concept: The ITU (UN agency for ICT, HQ Geneva) holds a Global Youth Summit to bring young people into digital policy.

1. The ITU Global Youth Summit 2025 (GYS-25) was held from 11 to 13 March 2025 in Varadero, Cuba.
2. Its theme was “Amplifying youth voices in ICT”.
3. Havana is Cuba’s capital, but the summit venue was the resort town of Varadero.

Yaad rakhein: GYS-25 → Cuba → Varadero (not Havana).

Answer: (D) Varadero, Cuba

Concept: In Windows 10, the time after which the screen turns off or the PC goes to sleep (power-saving) is set under Settings → System → Power & sleep.

1. Power & sleep lets you choose “Screen” and “Sleep” timings separately on battery and when plugged in.
2. Network & Internet handles Wi-Fi/Ethernet; Display handles brightness and resolution; Update & Security handles Windows Update.

Trick: Sleep timing → “Power & sleep”, the name itself says it.

Answer: (B) Power & Sleep Settings

Concept: Fundamental Duties (Part IV-A, Article 51A) were added on the recommendation of the Swaran Singh Committee.

1. The 42nd Amendment Act, 1976 inserted Article 51A with 10 duties (inspired by the USSR constitution).
2. The 86th Amendment, 2002 added the 11th duty (education of children aged 6 to 14).
3. The 44th Amendment (1978) removed property as a fundamental right; the 52nd (1985) is the anti-defection law.

Yaad rakhein: 42nd Amendment = “Mini Constitution” = Fundamental Duties + “Socialist, Secular” in the Preamble.

Answer: (C) 42^nd Amendment, 1976

Concept: In 1911 Rutherford fired alpha particles at a thin gold foil.

1. Most particles passed straight through → most of the atom is empty space.
2. A very few bounced back → all positive charge and almost all mass is packed in a tiny centre, the nucleus.
3. The electron was found by J.J. Thomson (1897), the neutron by Chadwick (1932), and the proton is credited to Rutherford’s later work (1917–19).

Yaad rakhein: Gold foil = nucleus discovered.

Answer: (C) Nucleus

Concept: Telangana’s long-term plan “Telangana Rising 2047” is aligned with the national goal of Viksit Bharat by 2047.

1. The vision document targets a $3 trillion State economy (GSDP) by 2047, the centenary of Independence.
2. 2030 and 2035 are interim milestones in many plans, but the 3-trillion goal is set for 2047.

Trick: Big “Viksit” targets of the Centre and states usually point to 2047 (100 years of Independence).

Answer: (A) 2047

Concept: Ctrl + C is the Copy command: it places a copy of the selected content on the clipboard without changing the document.

1. The selected paragraphs stay where they are; a copy goes to the clipboard.
2. They can then be pasted anywhere with Ctrl + V.
3. Deleting is Delete/Ctrl + X (cut), saving is Ctrl + S — not Ctrl + C.

Trick: C = Copy, X = Cut (scissors), V = Paste, S = Save.

Answer: (A) Transfers the highlighted paragraphs to clipboard for duplication elsewhere

Concept: An I/O device both takes data from the user and shows/gives results to the user.

1. A touchscreen displays output (screen) and accepts input by touch, so it is both.
2. Barcode reader and digital camera are input devices; a plotter is an output device.

Yaad rakhein: Common I/O devices: touchscreen, modem, headset (mic + speaker), network card.

Answer: (C) Touchscreen

Concept: Project Cheetah (launched 2022, Kuno National Park, MP) reintroduces cheetahs into India using animals from Africa.

1. In November 2025, during President Droupadi Murmu’s state visit, Botswana gifted India eight cheetahs.
2. The symbolic release took place at the Mokolodi Nature Reserve near Gaborone, Botswana.
3. Earlier batches came from Namibia (2022) and South Africa (2023).

Yaad rakhein: Mokolodi Nature Reserve is in Botswana — the place gives away the country.

Answer: (B) Botswana

1. In the Sustainable Development Report 2025, India ranked 99th out of 167 countries with a score of about 67.
2. This was the first time India entered the top 100 (it was 109th in 2024).
3. Finland topped the index.

Yaad rakhein: 2025 → India 99 (first time in top 100), score $\approx 67$.

Answer: (C) Rank 99 with an overall SDG index score close to 67 points

Concept: The Justice J.S. Verma Committee was set up to suggest ways to operationalise (put into practice) the Fundamental Duties.

1. The Verma Committee on Fundamental Duties of Citizens submitted its report in 1999.
2. It noted that some duties were already backed by laws, e.g. Prevention of Insults to National Honour Act, 1971.
3. Do not confuse it with the 2013 J.S. Verma Committee on criminal law (after the Delhi case).

Yaad rakhein: Swaran Singh (1976) recommended the duties; Verma (1999) on implementing them.

Answer: (A) 1999

Concept: The All England Open is one of the oldest and most prestigious badminton tournaments.

1. Prakash Padukone became the first Indian to win the All England men’s singles title in 1980.

Answer: (D) Prakash Padukone

Concept: The Balwant Rai Mehta Committee (appointed January 1957) reviewed the Community Development Programme.

1. It submitted its report in November 1957 and recommended “democratic decentralisation”.
2. It proposed a three-tier Panchayati Raj: village, block and district levels.
3. Rajasthan (Nagaur, 2 October 1959) was the first to adopt it.

Yaad rakhein: Mehta 1957 → three tiers; Ashok Mehta 1977 → two tiers.

Answer: (C) 1957

Concept: Overseas Citizenship of India (OCI) gives foreign nationals of Indian origin a lifelong multiple-entry visa, but it is not citizenship.

1. OCI cardholders cannot vote, cannot contest elections, and cannot hold constitutional posts or regular government jobs.
2. They also cannot buy agricultural/farm land.
3. They can study, work, pay taxes and own non-agricultural property in India.

Yaad rakhein: OCI = visa + most economic rights, but no political rights.

Answer: (C) Voting or holding a government job

Concept: Disguised (hidden) unemployment means more people are engaged in a work than are actually needed.

1. If some workers are removed, total output does not fall, so their marginal productivity is zero.
2. It is common in Indian agriculture, where many family members work on a small farm.
3. Option (A) is cyclical, (B) is frictional and (D) is voluntary unemployment.

Trick: Disguised = looks employed but adds nothing to output.

Answer: (C) More people are employed than actually needed, with marginal productivity being zero.

Concept: Census 2011 ranking of states by population: Uttar Pradesh, Maharashtra, Bihar, West Bengal, Andhra Pradesh (undivided).

1. Uttar Pradesh was first with about 19.98 crore people.
2. Maharashtra was second with about 11.24 crore.
3. Bihar (about 10.41 crore) was third and West Bengal fourth; Karnataka was much lower.

Trick: Population order: UP – Maha – Bihar – WB (“U M B W”).

Answer: (D) Maharashtra

Concept: If $a,b,c$ are in continued proportion, then $\frac{a}{b}=\frac{b}{c}$, i.e. $b^2=ac$ (the middle term is the mean proportional).

1. $\frac{2}{x}=\frac{x}{18}$
2. $x^2=2\times 18=36$
3. $x=\sqrt{36}=6$ (positive value)

Trick: Mean proportional of $a$ and $c$ is simply $\sqrt{ac}$: $\sqrt{2\times 18}=6$.

Answer: (C) $6$

Concept: When an amount is divided in the ratio $a:b$, the second share $=\frac{b}{a+b}\times \text{total}$.

1. Sum of ratio terms $=3+5=8$
2. B's share $=\frac{5}{8}\times 8400$
3. $=5\times 1050=5250$

Trick: One part $=\frac{8400}{8}=1050$; B gets $5$ parts $=5250$.

Answer: (C) ₹$5,250$

Concept: Let the son's present age be $x$; form an equation from the future condition (both ages increase equally).

1. Father $=3x$
2. After 15 years: $3x+15=2(x+15)$
3. $3x+15=2x+30\Rightarrow x=15$
4. Father $=3\times 15=45$ years

Trick: Check options: $45÷3=15$; after 15 years $60$ and $30$ — exactly double.

Answer: (B) $45$

Concept: Volume of a cylinder $V=\pi r^{2}h$.

1. $r=7\text{cm}$, $h=10\text{cm}$
2. $V=\frac{22}{7}\times 7\times 7\times 10$
3. $=22\times 7\times 10=1540{\text{cm}}^3$

Trick: With $r=7$, $\pi r^2=154$ always; just multiply by $h$: $154\times 10=1540$.

Answer: (C) $1540{\text{cm}}^3$

Concept: Number leaving the same remainder $r$ on division by several divisors $=k\times \text{LCM}+r$.

1. $\text{LCM}(14,15,8)=840$
2. $9999÷840$ gives quotient $11$ (since $11\times 840=9240$, $12\times 840=10080>9999$)
3. Required number $=9240+4=9244$

Trick: Largest 4-digit multiple of LCM, then add the remainder.

Answer: (D) $9244$
