Answer :

₹ 110000

Given :

Value of machine depreciates every year by 10 %

Present value of machine = ₹ 99000

To Find :

Value of machine in last year.

SolUtion :

Let the value of machine in last year be " M "

It depreciates by 10%, therefore, present value = 90% of M

According to question :

$\sf \dfrac{90}{100} \times {M} = \dfrac{9M}{10}$

$\sf \implies \dfrac{9M}{10} = 99000$

$\sf \implies M =\dfrac{99000\times 10}{9}$

$\sf \therefore M = 110000∴M=110000$

Hence,

Value of machine last year was ₹ 110000.
