Correct answer: B. about 26%
Worked solution
- Q3 total = 620.
- North's share = 160/620 ≈ 0.258 = about 26%.
Answer: about 26%.
The idea
Compute the column total first, then divide. Rounding only at the end keeps the answer accurate enough to match an option.
Shortcut. A quarter of the 620 total is 155, and North's 160 is just above it, so the share is a little over 25% — only 'about 26%' fits.
Common trap. "about 29%" — reading South's 180 instead of North's 160: 180/620 ≈ 29%.
