How many ATP molecules are produces from 1 molecule of Glucose?

Because I have learned that 38 ATP molecules are produced from 1 Glucose molecule this was given in NCERT books which are used to prepare for NEET exam but here in pearson and cambridge books it is given 30 - 32 ATP molecules, so what is the correct answer?

In Pearson’s Biology authored by Campbell et al 12th ed. page 169, for each molecule of glucose, the cellular respiration yields 32 ATP molecules, each with 7.3 Kcal/mole.
The 38 ATP was an old calculation also by Campbell, which I can remember from 2004. Not valid any longer!
