in the queue at the counter

by sanju09 » Fri Jul 30, 2010 4:23 am
How many people are standing in the queue at the counter?

1. If four more people join the queue, the number in the queue will be more than 15.
2. If three people give up and leave the queue, the number remaining will be less than 10.

n can be only integer.There cannot be 11 and half people or so :)
I think that sanju09 is asking how a number less than 11 can become 12. See your script one more time.
