Detailed Solution

Concept: Given that a bucket holds 13.5 litres of water and that it takes 12 buckets to fill a tank, we can simply multiply these two values to get the total volume of the tank, which comes out to be V=13.5×12=162.
The tank's volume or capacity is 162 litres as a result.
Now that we know how many buckets will be needed to fill the same tank with a bucket with a 9-litre capacity, we can simply divide it by the total volume of the tank we have. This gives us the answer: Therefore, the number of buckets needed for each bucket to transport 9 litres of water =162/9=18
Hence, the correct option is 4 .
