Hello aspirant,
Both CUET and DU might verify your income information during the admission process. This could involve asking for documents like income certificates. If there's a significant difference between the income figures you provide, it could raise red flags and lead to disqualification from the admission process.

These are the following things that you can do :

Double-check your income documents: Ensure you have the correct income figures for your category (EWS, OBC etc.)  These documents might be income certificates or tax returns.

Fill out the forms accurately: Use the same income figures from your verified documents in both the CUET and DU application forms.

Contact the admission authorities: If there's a genuine reason for a slight discrepancy (e.g., difference in financial year considered), proactively contact the admission authorities of both CUET and DU and explain the situation.

By following these steps, you can minimize the risk of any problems arising due to discrepancies in income information.

I hope this information helps.
