Eac [#permalink] 17 Jul 2018, 09:23 1 This post received KUDOS Paperbacks sell between$8 and $12 and there are altogether 200 paperbacks. Hence least price for the 200 paperbacks would be $$200 * 8 = 1600$$ While there are 100 hardcover and each sell for anything between$14 and \$18
The least the hardcover could sell for is $$14* 100 = 1400$$

Therefore the least average would be $$\frac{1600+1400}{300} = 10$$
For any other combination of price for paperback and hardcover the avg would be more than 10
