Rossari Biotech Ltd – Can growth justify expensive valuation?

Found something interesting but could not understand the logic. Appreciate if any member could help clarify this

They valued inv. in subsidiary – Rossari Personal Care at 27L (aprox) in FY21, sell 40% stake & buy back the same 40% at much higher value within a year itself & value the company at 2.27Cr?
A 10x jump in valuation.

I looked at revenue numbers for Rossari Personal Care too which were 4Cr in FY21 & 6Cr in FY22 (ref image)

So 10x jump in valuation or routing money?
Understand that 2Crs is small amt. in a 1600Cr rev comapany but am I looking at it correctly or missing something here?
