who is the richest person in the world and what is their net worth?
THE worldâs richest person got even richer this year. And a pair of tech gurus in their 20s made the list of the richest people in the world for the first time. Forbes said that Bill Gatesâs net worth rose to $79.2 billion in 2015 from $76 billion last year. That put him at the top of the magazineâs list of the worldâs billionaires for the second consecutive year. The co-founder of Microsoft Corp. has topped the list for 16 of the last 21 years.
