Answer 2

Answer:

Rs.25000

Step-by-step explanation:

Let the original cost be x

We are given that the value of machine depreciates every year by 10 %

So, Cost after 1 year = $x-\frac{10}{100}x$

Again the value of machine depreciates  by 10 %

Now amount of depreciation in second year =  $10\%(x-\frac{10}{100}x)$

We are given that the cost depreciates by Rs.2250 during second year

So,  $10\%(x-\frac{10}{100}x) = 2250$

$\frac{10}{100}(x-\frac{10}{100}x) = 2250$

$x=25000$

Hence The original value of machine is Rs.25000
