The property dealer suggested to Mr. Ansari that he should change names.

Explanation:
The suggestion of changing names by the property dealer is based on the assumption that Mr. Ansari might be facing discrimination or bias due to his name. By changing his name, it is implied that Mr. Ansari may be able to avoid any prejudice that he might be facing and improve his chances in the property market.

Changing names is a common practice in many societies and cultures, especially when individuals believe that their names might be a barrier to their success or acceptance. This can be particularly relevant in situations where there is a perceived bias or discrimination against certain names or ethnic backgrounds.

The property dealer's suggestion highlights the potential challenges that individuals like Mr. Ansari might face when it comes to property transactions. Discrimination in the real estate market is a well-documented issue in many countries, and individuals from certain ethnic or religious backgrounds may face prejudice when trying to buy or rent properties.

By suggesting a name change, the property dealer is proposing a solution that aims to overcome any potential bias or discrimination that Mr. Ansari might be experiencing. While changing names is a personal decision and might not be a guaranteed solution to the problem, it is seen as a way to potentially level the playing field and increase the chances of success in the property market.

Overall, the property dealer's suggestion reflects the reality of discrimination that some individuals face in the real estate market and highlights the measures that people might consider taking to navigate these challenges.
