the present price of a ceiling fan is 5670. If its value decreases every year by 10%, then find its value before 2 years.​

Answer 1

Answer:

Rs. 4592.7

Step-by-step explanation:

Present price of ceiling fan: Rs. 5670

Rate of value decrease per annum: 10%

Time (in years): 2

Value after 2 years: P×(1-R/100)^2

5670×(1-10/100)^2

5670×(1-1/10)^2

5670×[(10-1)/10]^2

5670×(9/10)^2

5670×9/10×9/10

4592.7

Hence, value of the fan will be Rs. 4592.7 after 2 years.
