How many bottles of 350 millilitres volume capacity be filled with 7 litre oil ?

Options

A. 2
B. 20
C. 200
D. 245

Answer

To solve the problem of how many bottles of 350 millilitres capacity can be filled with 7 litres of oil, we can follow these steps:

### Step 1: Convert litres to millilitres
We know that 1 litre is equal to 1000 millilitres. Therefore, to convert 7 litres to millilitres, we multiply by 1000.

\[ 7 \text{ litres} = 7 \times 1000 \text{ ml} = 7000 \text{ ml} \]

### Step 2: Determine the volume of one bottle
The volume capacity of one bottle is given as 350 millilitres.

### Step 3: Set up the equation
Let \( x \) be the number of bottles that can be filled. The total volume of \( x \) bottles can be expressed as:

\[ \text{Total volume of } x \text{ bottles} = x \times 350 \text{ ml} \]

### Step 4: Set the total volume equal to the available volume
We know that the total volume of oil available is 7000 ml. Therefore, we can set up the equation:

\[ x \times 350 \text{ ml} = 7000 \text{ ml} \]

### Step 5: Solve for \( x \)
To find \( x \), we can rearrange the equation:

\[ x = \frac{7000 \text{ ml}}{350 \text{ ml}} \]

### Step 6: Perform the division
Now, we divide 7000 by 350:

\[ x = \frac{7000}{350} = 20 \]

### Conclusion
Thus, the number of bottles that can be filled with 7 litres of oil is **20**.
