First colum 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%
Sorry could present the data in a tabular way.
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.
A) 6
B) 7
C) 13
D) 14
E) 29
This took me nearly 5 min and then finally followed POE to come with an ans.
I took a slightly different approach.
First I figured out the percentage change from the immediate previous amount for each of the period.Thus it comes-
0 - 6 days ==> 0%
7 - 13 days ==> 10% (90% of the price)
14 - 29 days ==> 17% (approx) (went from 90% to 75%)
30 days or more ==> 20% (went from 75% to 60%)
If the passenger had to pay the extra amount, she had to pay=(210+1050)=1260
now 210 is somehow between 10% and 20% of 1260. So 17% is the choice here. And correct ans: 14 days(d).
Though we do not need to do so many things when we have the option of eliminating some of the choices.
And Kudos for the post.
