How old is Andrés?
We know that the percentage in which the price decreases is equal to the age of Andrés.
We can write:
P = $4,000 = $40,000*(1 - k)
Where k is the percentage in decimal form.
Solving for k:
k = ($40,000 - $4,000)/$40,000 = 0.9
To obtain the percentage, we multiply by 100%.
0.9*100% = 90%
We conclude that Andrés is 90 years old.

I think this is one of the reducing fractions problem:
If we look at option A.{1/4} {1/5} {1/6} {1/7} {1/8}.
Here, the reduced form of all the fractions is not equal to 1/4
If we look at option B. <span>1/4,2/4,3/4,4/4,5/4.
</span>Here, the reduced form of all the fractions is not equal to 1/4<span>
if we look at option C. </span><span>1/4,2/8,3/12,4/16,5/20.
</span>Here, the reduced form of all the fractions is not equal to 1/4<span>
If we look at option D.</span>1/4,2/8,4/16,6/24,8/32.
Here, the reduced form of all the fractions is equal to 1/4
i.e.
1/4 = 1/4
2/8 = 1/4
4/14 = 1/4
6/24 = 1/4
5/20 = 1/4
So, the correct answer is D.
