You have some marbles, each of one colour of red, orange, yellow, green, blue, and violet.

The number of green marbles is one-quarter of the number of all of the other marbles.

The number of blue marbles is the square root of the number of orange marbles. (A square root of a number is a number that multiplied by itself equals the original number. The square root of 4 is 2 since 2 × 2 = 4.)

The number of red marbles is the cube of the number of violet marbles. (27 is the cube of 3 as 3 × 3 × 3 = 27.)

The six numbers of marbles are all different, and each is in the range of one to nine.

Given the above clues, how many of each colour do you have?
