# A queue of countries

This is a queue of countries:

$$Ireland, Guinea, Romania, Italy$$

Values:

$$Ireland = 7$$
$$Guinea = 15$$
$$Romania = 60$$
$$Italy = 87$$

Try to answer following questions:

1) $$Mali$$ = ?
2) $$Iran, rot. 90°$$ = ?
3) $$Bolivia, rot. 90°$$ = ?
4) $$Malta$$ = ?
5) $$Cameroon$$ = ?
6) $$Ukraine, rot. 90°$$ = ?
7) $$Ghana, rot. 90°$$ = ?
8) $$Bulgaria, rot. 90°$$ = ?

Hint 1:

Symbols such as stars in flags are unimportant

Hint 2:

Make a queue with the flags of the countries, in the right order.

Hint 3:

Try to create new flags with the queue.

• So it is first color times second color plus third color. – Duck Jun 29 '19 at 17:33
• Yes, that's true ! – Matti Jun 29 '19 at 17:36
• Are there three different shades of red here? And if it matters, in which direction are the rotations? – Weather Vane Jun 29 '19 at 18:28
• No there aren't different shades of red. The rotations can be in both directions, but if you have the right idea you will see it. – Matti Jun 29 '19 at 18:34

Making a queue of countries and finding the first appearance of each countries' flag, as well as @Duck's comment, i.e. first number times second number plus third (0 if no third number), I get:

1. $$Mali$$, Green Yellow Red (Guinea's flag reversed) $$9\times 2 + 3 = 21$$

2. $$Iran, rot. 90°$$, Same as Italy, $$87$$

3. $$Bolivia, rot. 90°$$, Same as Guinea $$15$$

4. $$Malta$$ = White and Red, no third color (Italy's flag) $$9\times 6 + 0 = 54$$
5. $$Cameroon$$ = $$9\times 4 + 8 = 44$$
6. $$Ukraine, rot. 90°$$ = $$7\times 8 = 56$$
7. $$Ghana, rot. 90°$$ = $$Guinea$$
8. $$Bulgaria, rot. 90°$$ = $$9\times 9 + 4 = 85$$
