People who register for a business conference and then cancel their registrations are subject to cancellation fees based on how far in advance they cancel, as shown in the table above. A certain executive who paid $2,000 to register for the conference was forced to cancel her registration and was charged a cancellation fee. How many days before the conference did she cancel her registration?

(1) If she had cancelled one day later, her cancellation fee would have been higher by $400.
(2) The cancellation fee was less than one-third of the registration fee.

OE
(1): Does not give info about executive’s refund
How much more executive cancellation fee would be if she cancelled one day earlier.
Won’t be able a distinct value for refund, but, using table to help, we would be able to find out what percent of $2000 is $400 and then compare that to table.
If that % is 10% or 50%, we should be able to find sufficiency. If it is 20%, our statement will be insufficient.
Since $400 = 20% of $2000, we know that executive must have cancelled on day 3 or 4.
No single value
Insufficient

(2): Table shows executive must have received refund on day 3 or 4. No other info.
Insufficient

Combined: (1) & (2) give same info
Insufficient


Hi, this is an unusual type of question.

(1) If she had cancelled one day later, her cancellation fee would have been higher by $400.

$400 is 20% of $2,000. Thus the registration was canceled 4 or 3 days before the conference (20% increment is from 4th to 3rd day and from 3rd to 2nd day). Not sufficient.

(2) The cancellation fee was less than one-third of the registration fee --> the cancellation fee was less than 33% --> the registration was canceled 5 or more, 4 or 3 days before the conference. Not sufficient.

(1)+(2) Still two possible answers: the registration was canceled 4 or 3 days before the conference. Not sufficient.

Answer: E.

here is how I approached this question:
Days prior to Conference Cancellation Fees
5 or more 0$
4 20$
3 600$
2 1000$
1 2000$

Clearly the executive cancelled on 3rd day because if she would have cancelled on 4th day then her cancellation fees would have been 1000$ which is 400$ more than cancellation fee on day 3

Why is A not the correct answer?

it could be 4 days also = 200 dollars cancellation fee ...one day later (3 days) would be 600 dollars which is 400 dollars higher than 200
