In a box of marbles, there are three less white marbles than the red ones and five more white marbles than the green ones. If there are a total of 10 white marbles, how many marbles are there in the box?
Number of white marbles = 10
Number of red marbles = 10 + 3 = 13
Number of green marbles = 10 - 5 = 5
Total marbles = 10 + 13 + 5 = 28
The correct option is A.
