Usually around 14 years old. Is the 1747 record from the Register of Duties paid for Apprenticeship Indentures 1710-1811? I did read that the date of payment listed in those registers was not always when the apprenticeship started though, so I would say your ancestor was born around 1732/1733 but the 1747 date may be when the duty was paid, and not always when the apprenticeship started.
