Which of the following is a prime number?
सही उत्तर: ख) 97
97 has no divisor other than 1 and itself. 91 = 7 × 13 is a common trap, as are 87 = 3 × 29 and 95 = 5 × 19.

The LCM of 12, 18 and 30 is:
सही उत्तर: घ) 180
12 = 2²×3, 18 = 2×3², 30 = 2×3×5; LCM = 2²×3²×5 = 180. 90 misses one factor of 2.

A train 150 m long crosses a bridge 250 m long in 20 seconds. The speed of the train is:
सही उत्तर: ग) 20 m/s
Distance covered = train + bridge = 400 m, so speed = 400/20 = 20 m/s. 12.5 m/s uses only the bridge length.

A car goes from A to B at 60 km/h and returns at 40 km/h. Its average speed for the whole journey is:
सही उत्तर: ख) 48 km/h
For equal distances, average speed = 2xy/(x + y) = 2 × 60 × 40/100 = 48 km/h. 50 km/h is the simple average, which is wrong because more time is spent at the slower speed.

A can do a work in 10 days and B in 15 days. Working together, they finish it in:
सही उत्तर: क) 6 days
Combined rate = 1/10 + 1/15 = 1/6 per day, so 6 days. 12.5 days is the average of the two times, which is not how rates combine.

If 12 workers can finish a job in 10 days, how many days will 8 workers take?
सही उत्तर: घ) 15 days
Work = 12 × 10 = 120 worker-days, so 8 workers need 120/8 = 15 days. Fewer workers need more days (inverse proportion).

Find the fourth proportional to 6, 9 and 10 (that is, 6 : 9 = 10 : x).
सही उत्तर: ग) 15
6 : 9 = 10 : x gives x = 9 × 10/6 = 15. 13 comes from adding 3, which treats a ratio as a difference.

Rs 3,600 is divided between A and B in the ratio 4 : 5. A's share is:
सही उत्तर: ख) Rs 1,600
Total parts = 9, so A gets 4/9 × 3,600 = Rs 1,600. Rs 2,000 is B's share.
