Correct answer: D
Concept
When a total is split among three categories, the missing category equals the total minus the other two categories.
If one category exceeds another by a stated difference, add that difference to the smaller category before finding the remaining category.
Application
For bakery A, American hotcakes = Cornmeal hotcakes + stated difference = 320 + 40 = 360.
Swedish hotcakes sold by bakery A = 1200 − 320 − 360 = 520.
Cornmeal hotcakes sold by bakeries A and D together = 320 + 420 = 740.
Required absolute difference = |740 − 520| = 220 hotcakes.
Cross-check
For bakery A, 320 + 360 + 520 = 1200, which matches the table total. Also, 740 − 520 = 220.
Therefore, the required difference is 220 hotcakes.
