Question

The value of a machine depreciates 10 every year. If it's present value is 387000 , what was its value1 year ago

Answer 1

Let us suppose the value of the machine an year ago=x.
It's 10% will be x*10%=x/10
If we analyze the question we can say that

X-X/10=387000
9X=3870000
X=3870000/9
Therefore X= Rs. 430000
