In a botanical garden, there are numerous trees, shrubs and plants. The four trees i.e. Neem, Bamboo, Banyan and Peepal are there in a row. There are ten trees between Bamboo tree and Banyan tree and five trees between Neem tree and Bamboo tree. If seven trees are between Banyan tree and Peepal tree, nine trees behind Peepal tree and $13$ trees ahead of Neem tree, then what could be the minimum numbers of tree in that row?
