Answer:

80kg

Step-by-step explanation:

100 + 10 = 110% (Percentage of gained weight)

110% = 88000

1% = 88000 ÷ 110 = 800

100% = 800 x 100 = 80000

Answer:

80kg

Step-by-step explanation:

let the normal weight be Y

88 = 10% of Y + Y

88 = 10/100 x Y + Y

88 = 0.1Y + Y

88 = 1.1Y

Divide both sides by 1.1

88/1.1 = 1.1Y/1.1

80 = Y
