To fill a tank, 25 buckets of water is required. How many buckets of water will be required to fill the same tank if the capacity of the bucket is reduced to two-fifth of its present ?
Answer: C
Let the capacity of 1 bucket \(= x\)
Then, the capacity of tank\( = 25x\)
New capacity of bucket \(=\dfrac {2}{5}x\)
\(\therefore\)Required number of buckets
\(=\dfrac {25x}{\left( \dfrac {2x}{5} \right)}\\
=\left( 25x \times \dfrac {5}{2x} \right)\\
=\dfrac {125}{2}\\
=62.5\)
