## Global Stats

Soni and Misha are exchanging stamps with each other. At the start, Soni has $$12$$ stamps of type $$X$$ and $$15$$ stamps of type $$Y$$ while Misha has $$20$$ stamps of type $$X$$ and $$10$$ stamps of type $$Y.$$ They have no other stamps of any other type with them apart from these. After the exchange, how many stamps of type $$Y$$ remain with Misha in total?

1) During the exchange, Soni gave exactly $$5$$ stamps of type $$X$$ to Misha and received exactly $$7$$ stamps of type $$Y$$ from Misha

2) After the exchange, number of stamps with Soni has increased by $$4$$
