Question

Price Check There is a shop with old-style cash registers. Rather than scanning items and pulling the price from a database, the price of each item is typed in manually. This method sometimes leads to errors. Given a list of items and their correct prices, compare the prices to those entered when each item was sold. Determine the number of errors in selling prices

Answer 1

Explanation:

The question statement is incomplete as it does not list the items and prices that have been entered manually as well as the correct prices of those items.

The modern method mentioned here is called POS, point of sale where a barcode scanner is usually used to input items and it makes an automatic list of all items purchased by a customer. It is fast, accurate and easier for cashiers to use.
