Question

The value of a machine depreciates every year by 10%.If the present value of the machine be
₹9900,What was its value last year?

Answer 1

Answer:

Heya ☺

Given that

Present value of a machine = ₹9,900

Rate of depreciation = 10 % p.a.

Time period = 1 year

Solution

Value of machine in last year = P(1-R/100)^n

=> 9,900 = P(1-10/100)

=> 9,900 = P(100-10/100)

=> 9,900 = P(90/100)

=> 9,900 = P × 9/10

=> P = 9,900 × 10/9

=> P = ₹11,000
