Question

12 buckets of water fill a tank when the capacity of each bucket is 13.5 liters. How many buckets will be needed to fill the same tank, if the capacity of each bucket is 9 liters?

• A. 8
• B. 16
• C. 15
• D. 18

Answer 1

The correct option is D 18

Capacity of the tank = (12×13.5) liters = 162 liters.
Capacity of each bucket = 9 liters
Number of buckets needed = $\left(\frac{162}{9}\right)=18$
