The price of the product before promotional sales was 500,000.
<h3>How to find out what the previous price was?</h3>
To find what the previous price of the product was, we must take into account that we know that 87% of the value is equal to 435,000. So to find out how much the 13% (discount) that the product had is equivalent to, we do the following operation:
435,000 × 100 ÷ 87 = 500,000
So we know that the 13% discount was 65,000

(I cannot draw the Venn diagram, sorry)
25 students in a class, 3 of them have neither -> Only 22 students have at least a pet.
15 of them have a cat, 16 of them have a dog -> There are 31 - 22 = 9 students that have both a cat and a dog
So, the probabilty of a person chosen at random that has a cat and a dog is 9 : 25 = 0.36 -> 36%.
