Speakers with Blue Teeth

Thursday 1st May 2025

Freddie returned a defective Bluetooth speaker to the shop and asked for his money back. By mistake, the shop assistant reversed the pounds and pence in the refund: the amount of pence was given as pounds, and the pounds were given as pence. Freddie did not notice and put the money in his pocket.

On his way home, he used £1.50 from the money in his pocket to buy a drink. When he got home, he counted the money left in his pocket and found he had exactly twice as much as the cost of the speaker.

What was the cost of the speaker?
