I think Toasty manipulated result cause she overheard Pashu saying that losing to younger brother will hit his self-esteem and not sure what to do where as Tej on winning does not want to run Chaturvedi Saree Bhandar as he wants to run his own store. She has done right in her own right by giving win-win to both brothers. However by manipulating results she is only deferring the impact of Pashu's failure which will hurt all relationships in house in future.
Pashu really need to reflect on his temper and 'why me' behavior to others and change for his own good.
Toasty also needs to learn that being sacrificial lamb all times is not good for her own being & Tej as an individual we have to respect ourselves first then only we can reciprocate respect to others.
