Explanation:
When revaluing non-depreciable assets like land, deferred tax must be accounted for on the revaluation surplus, which creates a temporary difference between the carrying amount of the asset and its tax base.

• Initial Revaluation of Land:
  The revaluation surplus on the land is GH¢15,000 (GH¢80,000 – GH¢65,000). Since the tax base is lower than the carrying amount, a deferred tax liability arises. The deferred tax liability is calculated based on the temporary difference, applying the tax rate to the revaluation surplus.
• Deferred Tax Calculation:
  The deferred tax on the revaluation surplus of GH¢15,000 is 25% x GH¢15,000 = GH¢3,750.
• Total Deferred Tax Liability:
  At 30 September 2017, the total deferred tax liability is GH¢6,750 (GH¢27,000 x 25%).
• Change in Deferred Tax Liability:
  The increase in the deferred tax liability from 1 October 2016 to 30 September 2017 is GH¢6,750 – GH¢2,600 = GH¢4,150. Of this amount, GH¢3,750 relates to the revaluation surplus and should be charged to other comprehensive income, while the remaining GH¢400 (GH¢4,150 – GH¢3,750) should be charged to the income statement.
