not really sure if Android tablet will be idle for office work (if its just reading Outlook email then fine) as for that price you can go for a i3 laptop for 25-30k during BBD or any sale time as you will have better screen estate and better configuration to work on..
just to watch media/office email & teams etc. I would go with Redmi/Realme pad i.e. around 15k and if budget is not a problem then you can go for your suggested ones..
