The correct option is
B 1804 km
To identify the distance between the recycling plant and the city, we have to find out the tens and the ones place with the help of the clues given in the question.
According to the first given clue, let us divide the digit at hundreds place by 2 to identify the ones place.
Digit at hundreds place = 8
Hence, the digit at ones place is:
8
÷ 2 = 4
Now, according to the second given clue, let us subtract the digit at thousands place by 1 to identify the tens place.
Digit at thousands place = 1
Hence, the digit at the tens place is:
1 - 1 = 0
Now, combining both the clues given together, we get:
Hence, the distance of the recycling plant from the city is 1804 km.
