Answer

To solve the problem of finding the weight of one lakh tablets, each weighing 25 mg, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the weight of one tablet**:
Each tablet weighs 25 mg.

2. **Determine the total number of tablets**:
We need to find the weight of 1 lakh tablets.
1 lakh = 100,000 tablets.

3. **Calculate the total weight in milligrams**:
To find the total weight of 1 lakh tablets, we multiply the weight of one tablet by the total number of tablets:
\[ \text{Total weight in mg} = \text{Weight of one tablet} \times \text{Number of tablets} = 25 \, \text{mg} \times 100,000 = 2,500,000 \, \text{mg} \]

4. **Convert milligrams to kilograms**:
Since 1 kg = 1,000,000 mg, we can convert the total weight from milligrams to kilograms by dividing by 1,000,000:
\[ \text{Total weight in kg} = \frac{2,500,000 \, \text{mg}}{1,000,000} = 2.5 \, \text{kg} \]

5. **Final answer**:
The weight of one lakh tablets is 2.5 kg.
