Question

The value of a machine depreciates 15% annually. If its present value is Rs 51,000. What was its value one year earlier ?​

Answer 1

Answer:

Rs. 60000

Step-by-step explanation:

Let the value be x

x - (15% × x) = 51000

x - (15/100 × x) = 51000

x - 3x/20 = 51000

(20x - 3x) /20 = 51000

17x/20 = 51000

x = 51000 × 20/17

x = 3000 × 20

x = Rs. 60000

Answer 2

Answer:

₹ 68,000

Step-by-step explanation:

Given,

Present value of machine = ₹ 51,000

Rate of depreciation = 15% annually

Then,

Let the price of machine 1 year ago be 'x'. Then,

According to the question,

x - (15% of x) = 51000

=> x - (15/100 × x) = 51000

=> 100x - 15x = 5100000

=> 75x = 5100000

=> x = 68000

Hence, value of machine one year ago would have been = x = ₹ 68,000
