Anandi might have invested part of Shiv's money. Just as some are assuming that she is spending all the money, one can assume that she might have invested some for her kids.
When CVs are not showing how anandi is maintaining a certain lifestyle, one cant assume either way.
She must be getting some salary for teaching karate. As a trustee for SN, she maybe entitled for her field trips and petrol expenses.
Here CVs are not interested about the financial aspects of their lead but about her story. We have to assume either way according to whether we want to support anandi or not. Just the way Ganga's education was assumed by Ganga's supporters and others.
We know dadisa is rich but what have we seen about the nitty gritties. How did they construct that hospital with all the facilities? How dadisa is able to buy so much gold? Same with Shekhars. Sanchi had her own car and spent laveshly on clothes and other things. IAS officer's salary is not that much to afford all those things. Maybe her father's earnings. But how much did he earn? If KB is daddu's property, what about Mahi's and Sanchi's share in it?
