The original price of a watch and a pair of trainers before the discount is £71.4
It is given that,
Before the discount, the trainer's were priced at £38
Before the discount, the total cost = trainer's cost + price of the watch.
⇒ 71.4 = 38 + price of the watch
⇒ Price of the watch = 71.4 - 38 = 33.4
∴ The price of the watch before the discount is £33.4
