Appeals partly allowed on assessment validity; interest disallowance upheld; unexplained investments partly allowed.

The appeals were partly allowed in the case regarding the validity of assessment and additions made by the Assessing Officer. The disallowance of interest was upheld for various assessment years due to the inability to prove business use of borrowed funds. Unexplained investments were partly allowed with relief granted based on the assessee's share in the firm M/s. Tirupati Construction Co. The Tribunal granted the benefit of disclosure/additions in the firm to the extent of the assessee's share in the profit and loss account for the relevant assessment years.
