Zen Ltd. is a manufacturing company with a 30 June year-end.

On 1 July 2018, Zen Ltd. purchased plant at the cost of R1 200 000. Depreciation is calculated over 15 years by using the straight-line method with the plant having an insignificant residual value. Zen Ltd.'s policy is to revalue the plant annually on 30 June and carry the plant at net replacement cost. They further realise revaluation surpluses while the relevant assets are used. The plant had the following gross replacement cost:

30 June 2019 R1 230 000

30 June 2020 R1 275 000

Revaluations are done by an independent appraiser who determines the replacement cost with reference to observable prices in an active market. On revaluation, accumulated depreciation is set off against the gross carrying amounts. The residual value and useful life of the plant were reassessed on 30 June 2020, and no changes were noted.

The South African Revenue Service grants a wear and tear allowance of 10% on the plant. Zen Ltd. intends to recover the carrying amount of the machine through use. Assume a tax rate of 28%.
