35 increased to 49

original amt=35
amt. of increase=49-35=14
percent increase=14%2F35=0.40=40%
60 is decreased to 15
original amt=60
amt of decrease=60-15=45
percent decrease=45%2F60=0.75=75%
99 is decreased to 69
original amt=99
amt of decrease=99-69=30
percent decrease=30%2F99=30.3%
83 is decreased to 0
original amt=83
amt of decrease=83-0-83
percent decrease=83%2F83=1=100%
