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 ?
10
35
62.5
Cannot be determined
Explanation:
Let the capacity of 1 bucket = $ x $.
Then, the capacity of tank = 25$ x $.
New capacity of bucket =$ \dfrac{2}{5} x $
$\therefore$ Required number of buckets =$ \dfrac{25x}{(2x/5)} $
=$ \left( 25x\times\dfrac{5}{2x} \right) $
=$ \dfrac{125}{2} $
= 62.5
