Explanation
The woman used one-fifth of 50 kg of wheat, which is: 50 kg × (1/5) = 10 kg
So, she used 10 kg of wheat to make bread.
She cooks two meals a day, which means she uses 20 kg of wheat per day.
To find out how much wheat she will use in two days, multiply the daily usage by 2:
20 kg/day × 2 days = 40 kg
Therefore, the correct answer is: 40 kg.
