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
