A number is such that it is as much greater than 84 as it is less than 108. Find the number.
Let us assume that the number is X.
So the equation we get from the problem:
X - 84 = 108 - X
X + X = 108 + 84
2X = 192
X = 192 / 2
X = 96.
Since 96 is (96-84=12) 12 more than 84 & (108 - 96 = 12) 12 less than 108.
Ans: 96.
