We have 25.20,25.25 and 25.00 ml.
 
Average=  
3
25.20+25.25+25.00
​ 
 
             =  
3
75.45
​ 
 
 
             = 25.15=25.1
 
In case of division, the final answer will contain as many significant figures as there are in an number with least significant numbers.
 
So, the significant number is 3.
