Dear Sunil Kumar thank you for your interesting technical question. There is no general answer to your question unless it is specified which kind of compounds you want to analyze by TLC. In general, you can combine any solvents you like, but the polarity of the solvents must match your compounds.
For some potentially useful general information please have a look at the following relevant articles:
Depends on you compounds, you may need to add 1% base (TEA) or acid (HOAC ) to move you compounds up on the TLC plate. The solubility of the compounds also need to be considered.
