Answer 1

Hey mark me as brainliest

Step-by-step explanation:

Let the cost price of 16 books be 16x

So, the selling price of 30 books = 16x

Cost price of 1 book = 16x/16 = x

Cost price of 30 Books = 30x

Since, Cost Price > Selling Price, there is a loss.

Loss = Cost Price - Selling Price

Loss = 30x - 16x

Loss = 14x

Loss % = Loss/Cost Price × 100

Loss % = 14x/30x × 100

Loss % = 46.67%
