- Mean is nothing but average
So Mean = (6+16+a+12/4)=14
=> (34+a/4)=14
=> a=22 - 11 years agoHelpfull: Yes(2) No(0)
- Ans: 22
The mean (average) of the given 4 numbers will be:
14 = (6+16+a+12) /4
Hence, (14*4) = (34 + a)
Hence, 56 = 34 + a
Hence, a = 56 - 34
Hence, a = 22 - 11 years agoHelpfull: Yes(1) No(0)
- mean=(6+16+a+12)/4
14=34+a/4
56=34+a
a=22 is the ans - 11 years agoHelpfull: Yes(0) No(0)
