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

Its so simple:
Just reverse the new capacity 2/5 into 5/2 then multiply it with 25.
25*5/2 = 62.5.

Let us assume the tank be 100 L.
For 100L tank, it takes 25 buckets
and the new dimension of the tank is 2/5 of 100 ie 40 L. so we don t know the no of buckets to be added.
100 L = 25 BUCKETS
40 L = X.
On cross multiplying, we get 10 buckets, then how 62.5 buckets came?

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.

It's simple.
2/5 = .40 = 40 percent.
25÷40 = 0.625 * 100 = 62.5.
2/5 = .40 = 40 percent.
25÷40 = 0.625 * 100 = 62.5.

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.

Consider bucket is of= 1ml.
The 25 bucket contain=25*1ml = 25ml.
If bucket reduced to 2/5 then to gain 25 ml we will choose one number which will give us required 25ml so,
2/5 * (62.5) = 25ml.
The 25 bucket contain=25*1ml = 25ml.
If bucket reduced to 2/5 then to gain 25 ml we will choose one number which will give us required 25ml so,
2/5 * (62.5) = 25ml.
