Gautamabhai knowingly or unknowingly has set an interesting and wise question paper for Ahilya . On top of that she even gave valuable clue which made Ahilya arrive at the correct answer.
Even Malhar and Tukoji did not give any hint or clue to Ahilya.
On top of everything else Gautama plays a fair game not letting yamunabhai interfere in Ahilyas quest for answers. May be it is the fear of Malhar’s anger.But she herself is helping Ahilya.
Malhar is disappointing letting her have her way. He should have stopped Gautama from having any condition for Ahilyas education
