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

Here question says 'reduce to' not 'reduce by'.
So, the capacity of the bucket is two-fifths of the present = 2x / 5.
25 = 2x/5
X = 62.5.
So, the capacity of the bucket is two-fifths of the present = 2x / 5.
25 = 2x/5
X = 62.5.

It's wrong. Because it said that it was reduced by 2/5.
So we have to subtract it from the original => x *-(2/5*).
So we have to subtract it from the original => x *-(2/5*).

A number of bucket=x.
Tank ,y=25.
y = (2/5)x.
25 = (2/5 )x.
x = 25*(5/2).
x = 125/2.
x = 62.5.
Tank ,y=25.
y = (2/5)x.
25 = (2/5 )x.
x = 25*(5/2).
x = 125/2.
x = 62.5.

When tanks capacity is being reduced how can you increase buckets quantity?
It's obvious buckets quantity is going reduce, right?

Simple explanation:
Let us assume tank capacity is 25 litres.
And each bucket has a capacity of 1 litre, which means 25 buckets is required to fill one tank.
Now each bucket capacity is reduced by 2/5 which means each bucket capacity is 0.4 litre
Now to fill a tank of 25 litre with 0.4 litre capacity bucket i.e 25/0.4 =62.5
Option C.
Let us assume tank capacity is 25 litres.
And each bucket has a capacity of 1 litre, which means 25 buckets is required to fill one tank.
Now each bucket capacity is reduced by 2/5 which means each bucket capacity is 0.4 litre

Option C.

Let the capacity of the tank be 100L.
25bucket fills 100L tank.
Therefore the capacity of each bucket is;
100/25 = 4L.
If the capacity of the bucket is reduced to 2/5th of before, then;
(2/5)*4 = 1.6.
To fill the tank of 100L=100/1.6.
= 62.5 buckets is required to fill the tank.
25bucket fills 100L tank.
Therefore the capacity of each bucket is;
100/25 = 4L.
If the capacity of the bucket is reduced to 2/5th of before, then;
(2/5)*4 = 1.6.
To fill the tank of 100L=100/1.6.
= 62.5 buckets is required to fill the tank.

How it can be more. Even its capacity is reduced. For reduced capacity, there must be less water needed. But 62.5 is more.
Could anyone help me out?

In the question, it is written that f "the capacity of the bucket is reduced to two-fifth of its present" which means;
If the present capacity is 100L and required 25 buckets to fill it.
Now it has been reduced to 2/5 i.e. 100*2/5 = 40L so now buckets required is 25*2/5 = 10 buckets.
If the present capacity is 100L and required 25 buckets to fill it.
Now it has been reduced to 2/5 i.e. 100*2/5 = 40L so now buckets required is 25*2/5 = 10 buckets.
