Answer 2

Answer:

value of the machine last year = Rs 110000.

Step-by-step explanation:

Let the value of machine last year be x Rs

Then, it's present value= 90%of Rs x

= Rs $(x \times \frac{90}{100} ) = Rs \frac{9x}{10}$

∴ $\frac{9x}{10} = 99000$=> $x = \frac{99000 \times 10}{9} = 110000$

∴ value of the machine last year = Rs 110000
