Question

4. The cost price of 16 books is equal to the selling price of 30 books . Find the loss%.

Answer 1

Answer:

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%

Answer 2

Answer:

Cost of 16 books is x

Cost of 1 book is x/16

Selling price of 30 books is x

Selling price of one book is x/30

Loss in one book is (x/16)-(x/30)=7x/240

Loss in x/16 is 7x/240

Loss in 15x/240 is 7x/240

Loss in 100=(7/15)*100=46.67%
