For a 13-month calendar, which distribution pattern places 4 months in the last quarter?

• A. 3-3-3-3
• B. 4-4-4-1
• C. 3-3-3-4
• D. 4-3-3-3

Answer: (C)

Distributing thirteen months across four quarters means the totals must add up to thirteen, so you’ll have three months in each of the first three quarters and four months in the last quarter. Three plus three plus three plus four equals thirteen, which places four months in the final quarter exactly as required.

Among the patterns shown, the one that ends with four months in the last quarter matches this setup. The others don’t: one pattern would put four months in the first quarter, another would end with just three months in the last quarter, and another would total twelve months if every quarter had three months. So the pattern that ends with four months is the correct match.
