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: Option
Explanation:
Let the capacity of 1 bucket = x.
Then, the capacity of tank = 25x.
| New capacity of bucket = | 2 | x |
| 5 |
 Required number of buckets = |
25x |
| (2x/5) |
| = |  25x |
x | 5 |  |
| 2x |
| = | 125 |
| 2 |
= 62.5

Let say 1 bucket holds 5 litre of water
So now its capacity is reduced to 2/5th i.e 5*2/5= 2 Litres
25 buckets fill the tank
Therefore, Tank's capacity is 25*5=625 litres.
Currently 1 bucket's capacity is 2 litres
Therefore buckets to fill 625 litres = 625/2=62.5
So now its capacity is reduced to 2/5th i.e 5*2/5= 2 Litres
25 buckets fill the tank
Therefore, Tank's capacity is 25*5=625 litres.
Currently 1 bucket's capacity is 2 litres
Therefore buckets to fill 625 litres = 625/2=62.5

You are rite but.
it is "reduced to 2/5" not "reduced by 2/5"
reduced to = 62.5
reduced by = 41.6
it is "reduced to 2/5" not "reduced by 2/5"
reduced to = 62.5
reduced by = 41.6
