Answer:
Let X be the value of the article.
The value of an article decreases for two years at the rate of 10% per year.
The value of the article at the end of
the 1st year is
X- 10% of X = 0.90X =
The value of the article at the end of
the 2nd year is
0.90X - 10% of (0.90X) = 0.81XThe value of the article increases in the 3rd year by 10%.
The value of the article at the end of
3rd year is
0.81x + 10% off (0.81x) = 0.891x =
The value of the article at the end of
3 years is Rs. 40,095.
0.891X = 40,095 - X
= 45,000
