The value of a machine depreciats 10% every year. If its persent value is ₹ 387000. What was it's value 1 year ago?
If its value last year was v, then
387000 = 0.9v
4300
387000 = (1-10/100). 387000=9/10 .cross multiplication 3870000/9 answer 43000
To find the value of the machine 1 year ago, we can use the concept of depreciation. If the value of the machine depreciates by 10% every year, it means that the machine retains 90% of its value each year.
1. Start with the current value of the machine, which is ₹ 387,000.
2. Calculate 90% of the current value to find the value retained after 1 year:
Value retained = (90/100) * Current value
= (90/100) * ₹ 387,000
3. Evaluate the expression to find the value retained:
Value retained = ₹ (0.9) * ₹ 387,000
= ₹ 348,300
Therefore, the value of the machine 1 year ago was ₹ 348,300.
