The correct Answer is:
To determine the best technique for checking the ink used at two different places in a document, we can analyze the options provided and their relevance to the task at hand. ### Step-by-Step Solution: 1. **Understanding the Problem**: The judge suspects that changes have been made to the documents and wants to analyze the ink used in different parts of the document. The goal is to identify whether the inks are the same or different. 2. **Evaluating Techniques**: - **Column Chromatography**: This method is typically used for separating larger quantities of substances and may not be ideal for analyzing small samples of ink. - **Solvent Extraction**: This technique is used to separate compounds based on their solubility in different solvents. While it can be useful, it may not provide the detailed separation needed for ink analysis. - **Distillation**: This method is used to separate components based on differences in boiling points. It is not suitable for analyzing inks, as inks are complex mixtures that do not separate effectively through distillation. - **Thin Layer Chromatography (TLC)**: This is an adsorption technique that allows for the separation of components in a mixture on a thin layer of adsorbent material. It is particularly effective for analyzing inks because it can separate the different dyes and pigments present in the ink. 3. **Conclusion**: Among the options provided, Thin Layer Chromatography (TLC) is the most suitable technique for analyzing the ink used in the documents. TLC will allow for the separation of different components of the ink, making it possible to compare the inks used in different parts of the document. ### Final Answer: The best technique to check the ink used at two different places in the documents is **Thin Layer Chromatography (TLC)**.

Karan Nath took over D' north Motor Company from his ailing father three months ago. In the past, the company was not performing well Karan was determined to improve the company's performance He observed that the methods of production as well as selection of employees in the company were not scientific He believed that there was only one best method to maximise efficiency He also felt that once the method is developed, the workers of the company should be trained to learn that 'best method He asked the Production Manager to develop the best method and carry out the necessary training. The Production Manager developed this method using several parameters right from deciding the sequence of operations, place for men, machines and raw materials till the delivery of the product to the customers. This methods was implemented throughout the organisation. It helped in increasing the output, improving the quality and reducing the cost and wastage Identify and explain the principles and the technique of scientific management followed by the Production Manager in the above case
