Concept: The Kalinga War was fought by Ashoka in about 261 BCE; its bloodshed made him turn to Buddhism.

1. Ashoka became king around 268 BCE (coronation) and invaded Kalinga (coastal Odisha) about eight years later, i.e. 261 BCE.
2. Rock Edict XIII describes the huge loss of life in Kalinga and Ashoka's remorse, after which he adopted Buddhism and Dhamma.
3. So the war came before his conversion; its date is 261 BCE.

Yaad rakhein: Kalinga = 261 BCE; remember "2-6-1: war, regret, Dhamma".

Answer: (B) 261 BCE

Concept: $\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}$ (not the average of the two speeds).

1. Total distance $=5+5=10\text{km}$
2. Time: morning $1\text{h}$, evening $1+0.5=1.5\text{h}$; total $2.5\text{h}$
3. Average speed $=\frac{10}{2.5}=4\text{km/h}$

Trick: Speeds are $5$ and $\frac{10}{3}$; for equal distances use $\frac{2xy}{x+y}=\frac{2\times 5\times \frac{10}{3}}{5+\frac{10}{3}}=4$.

Answer: (D) 4

Concept: Replace the letters by the signs and solve using BODMAS.

1. Replace: $19\times 4-7\times 8+32-11\times 2$
2. Multiplications first: $76-56+32-22$
3. Left to right: $20+32-22=30$

Trick: Do all × and ÷ first, then add all positives ($76+32=108$) and subtract all negatives ($56+22=78$): $108-78=30$.

Answer: (C) 30
