Solution
The correct option is B 4 pm
Given, the train starts at 8 am = 8 hours in 24-hour format.
And it takes 8 hours to reach at B.
So the train reaches B at 8 + 8 = 16 hours.
But in 12-hour clock, 16 hours is equal to 4 pm (as 16 - 12 = 4)
Hence, the train will reach city B by 4 pm (i.e. 4 in the evening)
4 pm
Given, the train starts at 8 am = 8 hours in 24-hour format.
And it takes 8 hours to reach at B.
So the train reaches B at 8 + 8 = 16 hours.
But in 12-hour clock, 16 hours is equal to 4 pm (as 16 - 12 = 4)
Hence, the train will reach city B by 4 pm (i.e. 4 in the evening)
