What if
Number of hardcover books =5
Number of soft cover books =10
They said: average price more than 14. That means together they are priced more than 28. We can assume together they can be 30 (average 15). If their combined prices are 30, according to statement they are priced software 10 and hard cover 20.
That means 5 hardcover book prices are 100 and and 10 softcover book prices are also 100.
I think the answer should be E. Please tell me where i am wrong.
