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?
সমাধান
সঠিক উত্তর: Option C
Let the capacity of 1 bucket = x.
Then, the capacity of tank = 25x.
New capacity of bucket = 2x/5
Required number of buckets = 25x/(2x/5)
= 62.5
