Concept: Application software is either general-purpose (off-the-shelf, used by anyone) or customized (tailor-made for one organisation's needs).

1. A payroll management system built for a specific company is customized software.
2. Spreadsheet, media player and image viewer are general-purpose packages.

Yaad rakhein: Made for one client → customized; sold to everyone → general-purpose.

Answer: (C) Payroll management system for a company

Concept: The 86th Constitutional Amendment Act, 2002 made elementary education a Fundamental Right (Article 21A).

1. It also added the 11th Fundamental Duty, Article 51A(k): a parent or guardian shall provide opportunities for education to his child/ward aged 6–14 years.
2. Protecting the environment, 51A(g), and safeguarding public property, 51A(i), came with the original 42nd Amendment (1976) list.

Yaad rakhein: DPSP/Fundamental Rights amendment → Parliament special majority + President's assent (mandatory, no veto).

Answer: (C) President's Assent

Concept: Heron's formula: Area $=\sqrt{s(s-a)(s-b)(s-c)}$ where $s=\frac{a+b+c}{2}$.

1. Sides $4:5:6$, perimeter $90$ → sides $=24,30,36$ cm and $s=45$.
2. Area $=\sqrt{45\times 21\times 15\times 9}=\sqrt{9^2\times 3^2\times 5^2\times 7}=135\sqrt{7}$.
3. With $\sqrt{7}=2.6$: area of $△PQR=135\times 2.6=351{\text{cm}}^2$.
4. Quadrilateral $=2\times 351=702{\text{cm}}^2$.

Trick: Break each factor into primes and pair them up before taking the root – $45·21·15·9$ gives $9·3·5$ outside and only $7$ left inside.

Answer: (B) $702{\text{cm}}^2$

Concept: Translate the sentence directly into an equation: $20\%$ of $x$ $-$ $20\%$ of $620=210$.

1. $20\%$ of $620=124$.
2. $\frac{20x}{100}=124+210=334$.
3. $x=334\times 5=1670$.

Trick: $20\%$ of the difference $=210$ ⇒ difference $=210\times 5=1050$; number $=620+1050=1670$. No fractions needed.

Answer: (C) 1670

Concept: Amount $=P{(1+\frac{r}{100})}^n$. Equal amounts after 15 and 16 years ⇒ the shares are in the ratio $1.1:1$.

1. Anil $\times (1.1{)}^{15}=$ Ashok $\times (1.1{)}^{16}$ ⇒ Anil $=1.1\times$ Ashok.
2. Anil : Ashok $=11:10$, total $21$ parts $=1407$ ⇒ 1 part $=67$.
3. Ashok $=10\times 67=$ ₹$670$.

Trick: "Same amount after $n$ and $n+1$ years" ⇒ divide in ratio $(100+r):100$. Here $110:100=11:10$.

Answer: (D) ₹670
