1. 1. A train 150 m long is running at 72 km/h. How long will it take to cross a platform 250 m long?

   • A.15 s
   • B.18 s
   • C.20 sCorrect
   • D.24 s

   72 km/h = 72 × 5/18 = 20 m/s. Total distance = 150 + 250 = 400 m. Time = 400 ÷ 20 = 20 s.

   • A.0
   • B.5
   • C.7Correct
   • D.14

   At 25°C, a neutral aqueous solution has pH = 7; values below 7 are acidic and above 7 are basic.

4. 4. Which cell organelle is commonly known as the ‘powerhouse of the cell’ because it generates ATP?

   • A.Ribosome
   • B.MitochondriaCorrect
   • C.Golgi apparatus
   • D.Lysosome

   Mitochondria produce ATP through cellular respiration.

5. 5. Find the missing number in the series: 4, 9, 19, 39, ?

   • A.69
   • B.78
   • C.79Correct
   • D.81

   Each term = previous term × 2 + 1: 4×2+1=9, 9×2+1=19, 19×2+1=39, 39×2+1=79.

6. 6. If 18 workers can build a wall in 10 days, how many days will 15 workers take at the same rate?

   • A.11 days
   • B.12 daysCorrect
   • C.14 days
   • D.15 days

   Total work = 18 × 10 = 180 worker-days. For 15 workers: 180 ÷ 15 = 12 days.
