Some birds were flying and met a bird on their way. The bird greeted them; "hello hundred" They said, "we are not hundred; we need half of us plus you to make us hundred". Q. How many birds were flying?

198 birds

if they say they need half of them plus that one bird, then that means they are 198, because half of 198 is 99, plus one makes 100.
