• A. 201
• B. 387
• C. 796

Answer 1

The correct option is B 387

Number of passengers in each compartment is 43.
The train has a total of 9 compartments.
$\therefore$ Total number of passengers in the train $=43\times 9$
For estimation we round the number to tens place.

• Rounding off of 43 to tens place = 40
• Rounding off of 9 to tens place = 10

$\Rightarrow$ Estimated total number of passengers $=40\times 10=400$
From the given options, 387 is closest to 400.
$\therefore$ Actual total number of passengers in the train is 387.
