In 2014 , 2277 was 110% of 2013.

Number in 2013 = 90% of the year before (2012)

Let the number in 2013 be x. From the first statement,

2277 = 110% of x

2277 = (110/100)x

2277 = 1.10x

x = 2277/1.1 = 2070

Number in 2013 is 2070

Number in 2013 = 90% Number in 2012

2070 = (90/100) * Number in 2012

2070 = 0.90 * Number in 2012

2070 / 0.90 = Number in 2012

2300 = Number in 2012

Number in 2012 = 2300
