Table: Business permits issued by a municipal office — January 120, February 150, March 180, April 150. March permits make up what percentage of the four-month total?
Correct answer: D. 30%
March share = 180 ÷ 600 × 100 = 30%. Check: 30% of 600 is 180. A share is always part ÷ whole, so the four-month total goes in the denominator.
