The average weight of a car is 1,425 kg. A car carrier can take up to 9 cars. The car carrier takes about ___________ kg if it is fully loaded up?

The correct answer is: 13000

1,425 × 9 = 12,825 kg

Weight of one car is equal to 1425 kg. Weight of nine such cars is equal to 9 x 1425 kg = 12825 kg, which can be rounded off to 13000 kg when fully loaded up.
