Answer 2

ANSWER :

• The value of machine a year ago is 430000.

GIVEN :

• The value of a machine depreciates every year.
• The present value of a machine is ₹ 38700.

TO CALCULATE :

• The value of a machine a year ago = ?

SOLUTION :

Let the value of the machine be 'x' a year ago.

The 10% of a machine will be $\sf x \times 10 \% \ = \ \dfrac {x}{10}$

Now,

$\implies \sf x \ - \ \dfrac {x}{10} \ = \ 387000$

$\implies \sf 9 x \ = \ 3870000$

$\implies \sf x \ = \ \dfrac {3870000}{9}$

$\qquad \qquad \large \blue {\boxed {\sf x \ = \ 430000}}$

•°• The value of machine a year ago is 430000.
