A company selected 250 zip codes in Northeastern, Florida, Arizona and California in order to mail a product catalog. The number of Northeastern zip codes was twice Florida's, and four times Arizona's, and 4/3 California's. 375,000 catalogues were mailed to California and 25% resulted in product orders. What is the ratio of the number of orders to the number of California's zip codes? Choose the correct choice from the following
A) a) 500  B) b) 750  C) c) 1,000  D) d) 1,250  E) e) 1,500
Since N = 2F, no of Florida zip codes (F) will be N/2.   Since N = 4A, no of Arizona zip codes (A) will be N/4   Since N = (4/3)C, no of California zip codes (C) will be 3N/4   N + N/2 + N/4 + 3N/4 = 5N/2 = 250   N = 100   C = 3N/4 = 75   No of orders is 25% of 375,000 = 93,750   So required ratio = 93,750/75 =1,250   Answer d) 1,250
