Sagot :
Using proportions, it is found that both can be right, as the amounts found from each operation are the same.
What is a proportion?
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Considering you have 73 cards, and your cousin says that you have 7 less than half the cards he has, his amount is found as follows:
0.5x - 7 = 73
0.5x = 80
x = 160.
Then, one-fourth of his amount is:
(1/4) x 160 = 40.
33 more than this is:
33 + 40 = 73.
Both operations have results (73,160), hence the both can be right.
