Answer 2

❍ Given :-

• 3 muffins and 4 doughnuts weighs 580g
• Mass of 3 muffins is 180g

❍ To Find :-

• Mass of each doughnut

❍ Solution :-

➸ Weight of 4 doughnuts = (Weight of 3 muffins and 4 doughnuts) - Weight of 3 muffins

= 580g - 180g

➸ Weight of one doughnut =$\sf \dfrac{400}{4}g$= 100g

Therefore, mass of each doughnut is 100g.
