In a software development company 30% workers are B.Tech degree holders,25% are MBAs, and 20% hold both these degrees.If325 workers are without any professional degree,how many workers are there in the company in all?

• The no of workers having B.tech or mba degree is 30+25-20=35
  so the no of workers without any professional degree=100-35=65
  then 65% of x=325
  so x=500 where x is the total no of workers.
