First column specifies the No of Days prior to departure information. Second column specifies the Percentage discount offered.
0 - 6 days ==> 0%
7 - 13 days ==> 10%
14 - 29 days ==> 25%
30 days or more ==> 40%
The table above shows the discount structure for advanced purchase of tickets at a particular airline. A passenger bought a ticket at this airline for $ 1050. The ticket agent informed her that, had she purchased the ticket one day later, she would have paid $210 more. How many days before her departure did she purchase her ticket. Choose the correct option:
A) 6	B) 7	C) 13	D) 14	E) 29
First I figured out the percentage change from the immediate previous amount for each of the period.Thus it comes-   0 - 6 days ==&gt; 0%   7 - 13 days ==&gt; 10% (90% of the price)   14 - 29 days ==&gt; 17% (approx) (went from 90% to 75%)   30 days or more ==&gt; 20% (went from 75% to 60%)   If the passenger had to pay the extra amount, she had to pay=(210+1050)=

<output>1_260</output>
1260   now 210 is somehow between 10% and 20% of 1260. So 17% is the choice here.   correct ans: 14 days   ANSWER:14
<result>D</result>
