Give stream of consciousness and then the final answer. In a locality, the prevailing price of a 700 square feet property last year was US Dollar 1000. The owner made some additions and the 900 square feet property is now fetching a price of US Dollar 1500. By approximately what percent did the ratio of price to size increase from the previous year's price?
Options:
(A) 12
(B) 14
(C) 17
(D) 21
(E) 19
Initial price/area ratio = 1000/700 = 9000/6300
Revised mileage/weight ratio = 1500/900 = 10500/6300
The final answer: (C).
