Question

A manufacturer estimates that his machine depreciates by $15$ of its value at the begining of the year. Find the original value (cost) of the machine, it it depreciates by $Rs.5,355$ during the second year.

Answer 1

given depriciated by 5,355 for second year.

i.e., $15\%=5355$

$100\%=?$

$=\frac{100\%\times 5355}{15}=35,700$

i.e., the value ($35,700$) after depreciation for 1st year by $15\%$

$85\%-35,700$

$100\%=?$

$=\frac{100\times 35,700}{85}=42,000$

$\therefore$ the original cost of machine = $42000$Rs
