a) 2277 =  110% of number in 2013

b) Number in 2013 = 90% of year before, 2012


2277 = 110% of Number in 2103

2277 = (110/100) * Number in 2013

2277 * 100/110   =  Number in 2013

2070 =   Number in 2013

Number in 2013 is = 2070

b) Number in 2013 = 90% of year before, 2012

     2070  =  (90/100) * Number in 2012

     2070 * 100/90  =  Number in 2012

     2300 =    Number in 2012

Hence number in 2012 =  2300 student athletes.
