let's say attendance in 2010: x
20% greater in 2012: 6x/5
attendance in 2011: y
5% greater in 2012: 21y/20
attendance in 2012: 6x/5 = 21y/20, y = 24x/21
percent increase from 2010 to 2011: (y-x)/x *100 = ((24x/21)-x)/x *100 = 3x/21x *100 = 14.2871
Ans: 14.286
20% greater in 2012: 6x/5
attendance in 2011: y
5% greater in 2012: 21y/20
attendance in 2012: 6x/5 = 21y/20, y = 24x/21
percent increase from 2010 to 2011: (y-x)/x *100 = ((24x/21)-x)/x *100 = 3x/21x *100 = 14.2871
Ans: 14.286
