Answer:
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%
