P/E, P/B and ROE are inconsistent: ROE x P/E = 2.77 but P/B = 3.75 (> 25% apart); one input is likely on a different basis. Our computed roe (10.01%) diverges from BSE's own published figure (23.19%) by more than 100%. BSE's figure is a different, BSE-computed number (not necessarily TTM, standalone-only) — treat as a cross-check/fallback signal, not proof either figure is wrong.
