68. N is the number of products being sold.
If N < 10, each product is sold at $200.
If 10 <= N < 20, each product is sold at $10 plus a fixed charge of $100.
If N >= 20, each product is sold at $20.

(Note that if N is 11, 10 products are sold at $200 each, and 1 product is sold at $10 plus a fixed charge of $100.)

How many products were sold yesterday?

1) Yesterday 2 more products were sold than today.
2) The revenue from yesterday is by $10 greater than today's revenue.

(Please show your workings ... what formular could be made if this were PS? ) _________________

well, i think what matters here is that we shouldn't understand the number of products sold starts from 0 each day ....instead, we should understand that the number of ticket sold yesterday is an accumulated number from the day before, before before yesterday and so forth.

I still think it is E.
1) does not give out anything
2) says that the no of products sold on both days falls in the 10-20 category and one book extra was sold yesterday.
But it can be 12 and 11 or 13 and 12 etc. -- insuff

1 and 2-- could not get any nos that satisfy this. -- insuf

If I understand the stem correctly, each product is worth of at least $10 or more, and thus two extra product would be worth of at least $20. From (2) we know yesterday's number is between 11 and 17. Combine (1) and (2) there is no possible solution.

Or let's look at it in more details:
Let x be yesterday's number. Two more products would result in the following revenue differences:

If x<=8, the rev difference would be $400.
If x=9, the rev difference would be $310.
If x=10, the rev difference would be $120.
If 11<=x<=17, the rev difference would be $20.
If x=18, the rev difference would be $30.
If x>=19, the rev difference would be $40.

The only occasions where we would be able to determine x would be if (2) says the revenue difference is 310, 120, or 30. _________________
