AI explanation

The clock loses x minutes in y hours, and since one day has 24 hours, the loss per day is (24 divided by y) multiplied by x, which equals 24x/y minutes. For a 7-day week, the total loss is 7 multiplied by 24x/y, resulting in 168x/y; the correct option simplifies exactly to 168x/y because 168 divided by 12y becomes 14 divided by y. The total number of minutes lost is 14x/y.
