A dietitian records information for two adults in a weight-management programme. Each adult's height stayed unchanged during the programme.
| Adult | Height in m | BMI at the start | Mass lost so far in kg |
|---|---|---|---|
| J | 1.68 | 31.0 | 3.5 |
| K | 1.82 | 29.0 | 2.0 |
Use the equation.
BMI=mass in kg(height in m)2 \text{BMI}=\frac{\text{mass in kg}}{(\text{height in m})^2} BMI=(height in m)2mass in kgCalculate which adult must lose the greater additional mass to reach a BMI of 25.0, and by how much.
