Ques:- A man sees a train passing over a bridge 1 km long. The length of the train is half that of the bridge. If the train clears the bridge in 2 minutes, the speed of the train is
A. 30 km/hr
B. 40 km/hr
C. 45 km/hr
D. 55 km/hr
Right Answer:
  • Length of the bridge = 1 km = 1000 meters

  • Length of the train = ½ of the bridge = ½ × 1000 = 500 meters

  • Time taken to cross the bridge = 2 minutes = 2 × 60 = 120 seconds

When a train clears a bridge, it travels a distance equal to the length of the train plus the length of the bridge.

So, total distance = 1000 m + 500 m = 1500 meters
Time = 120 seconds

Now, use the speed formula:

Speed = Distance / Time
= 1500 m / 120 s
= 12.5 meters per second

To convert this to km/h:

Speed in km/h = 12.5 × 18 / 5 = 45 km/h

✅ Final Answer: 45 km/h

Ques:- How would you manage two projects that require your time?
Right Answer:

If I had to manage two projects at the same time, I’d start by understanding the priorities, deadlines, and resource needs for both. I’d create a schedule that breaks down tasks day by day, set realistic milestones, and communicate regularly with both teams. Time management, setting clear expectations, and staying organized are key. I’d also be flexible—if one project needs urgent attention, I’d adjust while keeping the other on track. Balance and communication make it possible.

Ques:- 2056 x 987 = ?
A. 1896172
B. 1936372
C. 1923472
D. 2029272
Right Answer:

Let’s calculate:

2056 × 987

We can break 987 as:

987 = 1000 − 13

Now,

2056 × 987 = 2056 × (1000 − 13)
= 2056 × 1000 − 2056 × 13
= 2,056,000 − (2056 × 13)

Now calculate 2056 × 13:

2056 × 13 = (2000 + 56) × 13
= (2000 × 13) + (56 × 13)
= 26,000 + 728 = 26,728

Now subtract:

2,056,000 − 26,728 = 2,029,272

✅ Final Answer:
2056 × 987 = 2,029,272
