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. 450,000 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 answers:
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 450,000 = 112,500   So required ratio = 112,500/75 = 1500   Answerr e) 1,500
