Question

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

• A. $8$
• B. $15$
• C. $16$
• D. $18$

Answer 1

Answer: (D)

$18$

total volume of tank is $13.5\times 12=162$

volume of tank will remain same , let number of buckets be $x$

so $9x=162$

$x=18$

Hence Option D is correct
