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 bucket size is 100 ml.
Tank size = 25*100 = 2500ml.
New bucket size = 2/5*100 = 40 ml.
Buckets required to fill 2500ml tank with 40 ml bucket = 2500/40 = 62.5.
Tank size = 25*100 = 2500ml.
New bucket size = 2/5*100 = 40 ml.
Buckets required to fill 2500ml tank with 40 ml bucket = 2500/40 = 62.5.

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?

2/5 present bucket = 1 previous bucket,
So 1 present bucket =5/2 the previous bucket,
So 25 present bucket = 25 * 5/2 bucket,
= 62.5 bucket.
So 1 present bucket =5/2 the previous bucket,
So 25 present bucket = 25 * 5/2 bucket,
= 62.5 bucket.

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.

Simple one:
New bucket size is 2/5 of old one
So just do =25*5/2(here 25 old buckets are needed to fill the tank)
=62.5
New bucket size is 2/5 of old one
So just do =25*5/2(here 25 old buckets are needed to fill the tank)
=62.5

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

2x/5 =25 bucket.
2x = 125 =(5*25),
X = 125/2,
X = 62.5.
Or.
1 bucket = 2.5.
25 bucket = 25 *2.5,
= 62.5.
2x = 125 =(5*25),
X = 125/2,
X = 62.5.
Or.
1 bucket = 2.5.
25 bucket = 25 *2.5,
= 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

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*).
