Hello Nicolás,

Of course, you can also do this with the Calculated question. Take question # 7, which is a Calculated question, from the Demo Quiz with all standard Quiz Questions. Let's say we want x (complete beginners) to be a multiple of 10 between 10 and 100, and y (relatively experienced Moodle users) to be a multiple of 10 between 100 and 200.

#### "Editing a Calculated question" page

Question text: ... In your group you have {={x}*10} complete beginners and {={y}*10} relatively experienced Moodle users.

Answer 1 formula = {x}*10 + {y}*10

#### "Edit the wildcards datasets" page

Wild card {x}

Range of values: Minimum: 1 - Maximum: 10

Decimal places: 0

Wild card {y}

Range of values: Minimum: 10 - Maximum: 20

Decimal places: 1

With the Formulas question, you just need:

Random variables:

x={10:110:10};

y={100:210:10;}

Question text: ... In your group you have {x} complete beginners and {y} relatively experienced Moodle users.

Answer: x + y
