The six notes are £5, £5, £10, £20, £20, £20.
Step-by-step explanation:
Tom has six banknotes.
The value of each is £5 or £10 or £20.
He can make £20 with three notes.
£20 = £5 + £5 + £10 [He has two £5 notes and one £10 note]
He can make £55 with four notes.
£55 = £5 + £10 + £20 + £20 [He has two £20 notes, one £10 note and one £5 note]
He cannot make £25 with three notes.
£25 = £5 + £10 + £10 [He don't have two £10 notes]
He cannot make £25 with four notes.
£25 = £5 + £5 + £5 + £10 [He don't have three £5 notes]
Hence, the six notes are £5, £5, £10, £20, £20, £20.
