correct answer is 28.
If the mean of four numbers is 25 and three numbers are 36, 12 and 24 then fourth number is 28.
given terms are:
first number =36
second number=12
third number=24
fourth number=?
let us assume the fourth number be x.
we know the formula to find mean is:
Mean=addition of given terms / total number of terms
According to given statement, we put the values in above equation and we get,
25=(36+12+24+x) / 4
By rearranging, we get
36+12+24+x=100
72+x=100
x=100-72
x=28
so, the fourth number is 28.
