Question

The value of a machine depreciates by 10% every year. If its present value is ₹35100, what was its value a 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=35100
9X=351000
X=35100/9
Therefore X= Rs. 39000
