Question no. 2

Answer 1

let the value of machine=100(p)
rate=10%
value of machine at the end of year=100-100×10÷100
100-10=90
rate of depreciation fr 2nd yr=10
value of machine at end of 2nd yr=90-90×10÷100=90-9=81
rate of depreciation at the end of third year=15%
81-81×15÷100=68.85
total depreciation=100-68.85=31.15
percentage of depreciation=31.15×100÷100
=31.15%
