Answer: 12y</h3>
=====================================================
Explanation:
4y is the middle value, or second value.
This means 4y-1 is the first value since it is immediately before 4y
Also, we know that 4y+1 is the value just after 4y
The order of the terms is: 4y-1, 4y, 4y+1
Add up those three expressions and simplify
(4y-1) + (4y) + (4y+1)
4y-1 + 4y + 4y+1
(4y+4y+4y) + (-1+1)
12y+0
12y
The three terms combine to 12y.
Let 'x' be the initial weight of Hamid.
He gained 0.10x kg (10% of his first weight)
His current weight:
0.10x + x = 88
1.10x = 88
x = 88/1.10
x = 80 kg
