x/5=27
x= 27×5
x=135 ; 135 is the sum of the numbers
; there are total 5 numbers in the sum
; their mean is 27
reduced by 2= sum -3
= 135-2
=133
now divide 133/5
=26.6
26.6 is the excluded number

Step-by-step explanation:
Mean of 5 numbers =27
sum of 5 numbers =5*27=135
mean got reduced by 2 after one number is excluded
therefore for new mean =25
sum of remaining four number =25*4=100
Value of excluded number =135-100=35
