What is the formula for calculating the alpha-tocopherol equivalents?

$mg \alpha-tocopherol + mg \beta-tocopherol + mg \gamma-tocopherol + mg \alpha-tocotrienol$

$mg \alpha-tocopherol + 2 \times mg \beta-tocopherol + 0.1 \times mg \gamma-tocopherol + 0.3 \times mg \alpha-tocotrienol$

$mg \alpha-tocopherol + 0.5 \times mg \beta-tocopherol + 0.2 \times mg \gamma-tocopherol + 0.3 \times mg \alpha-tocotrienol$

$mg \alpha-tocopherol + 0.5 \times mg \beta-tocopherol + 0.1 \times mg \gamma-tocopherol + 0.3 \times mg \alpha-tocotrienol$ (correct)
