Here, present value = ₹112000
rate of depreciation = 15% per annum and n = 3 yr.
{tex}\therefore{/tex} Value after 3 yr = 112000{tex}\left(1-\frac{15}{100}\right)^{3}{/tex}
= {tex}\left[112000 \times\left(\frac{85}{100}\right)^{3}\right]{/tex}
= {tex}\left(112000 \times \frac{17}{20} \times \frac{17}{20} \times \frac{17}{20}\right){/tex}
= (14 {tex}\times{/tex} 17 {tex}\times{/tex} 17 {tex}\times{/tex} 17) = ₹68782
