  A survey was conducted on a car brand Khatara . It was found that 60% of vehicles had a problem with their engines , 60% of vehicles had a problem with their doors and 50% with tyres and 20% had no problem.. what is the min and max percentage of vehicles that have had all problems?

Min case : 80 80 30 nd Max case: 80 60 50................. 1
