Best answer
Correct Answer - Option 2 : Rs. 3905

Given:

The present value of the machine is Rs. 5800

1st year depreciate value = 10%

2nd year depreciate value = 12%

3rd year depreciate value = 15%

Formula used:

Decreased value = Initial value × (100 - decrease%)/100

Calculation:

Value of machine after 1 year

5800 × 90/100 = Rs. 5220

Value of machine after 2 year

5220 × 88/100 = Rs.4593.6

Value of machine after 3 year

4593.6 × 85/100 = Rs. 3904.56 ≈ Rs. 3905

∴ The value of the machine after 3 years is Rs. 3905
