Concept: The Paika Rebellion was an armed uprising of the Paikas (traditional militia) of Khurda, Odisha, against British rule.

1. It broke out in 1817 under Bakshi Jagabandhu, military chief of the Raja of Khurda.
2. Causes: the new British land-revenue settlement, loss of Paika rent-free lands and rising salt prices.
3. 1806 is the Vellore Mutiny year – a common trap.

Yaad rakhein: Khurda + Bakshi Jagabandhu = 1817; it is sometimes called the "first war of independence" of Odisha.

Answer: (D) 1817

Concept: If $a_1{x}^2+b_{1}x+c_1=0$ and $a_2{x}^2+b_{2}x+c_2=0$ have both roots common, then $\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}$.

1. $\frac{2}{3}=\frac{K}{4}=\frac{8}{12}$
2. $\frac{8}{12}=\frac{2}{3}$ ✓ (consistent)
3. $\frac{K}{4}=\frac{2}{3}\Rightarrow K=\frac{8}{3}$

Trick: Both roots common ⇒ the two equations are multiples of each other.

Answer: (A) $\frac{8}{3}$

Concept: Replace each sign by its meaning, then solve using BODMAS.

1. Given: $32÷14+16-8\times 4$
2. Replace (÷→+, +→−, −→×, ×→÷): $32+14-16\times 8÷4$
3. $16\times 8÷4=32$, so $32+14-32=14$

Trick: Write the new expression first, then apply BODMAS – never solve before replacing signs.

Answer: (A) 14
