Answer 1

Answer:

$50\%$

Step-by-step explanation:

Previous Iron content per serving=1.2 mg

Current Iron content per serving=1.8 mg

Increase in Iron content per serving=1.8-1.2=0.6 mg

Percentage of Iron Increase

$=\dfrac{\text{Increase in Iron Content}}{\text{Previous Iron Content}} X 100\\=\dfrac{0.6}{1.2}X100 \\=50\%$
