بسم الله الرحمن الرحيم
(Fatwa: 1031/984/B=12/1437)
If you have bought the shop with the intention of selling then the shop became business property for you. You will have to pay fortieth part of the amount in zakah which might be the price of similar shop. You and both of your brothers i.e. the trio shall share it.
Allah knows Best!
