# color coded puzzle

Help me solve this problem. As this site appreciates a little effort from the person who posted it. Here's my thought process:

1) The matrix starts with 0 ( gr, gr, gr). It has three places which can take two different colors green and red so within the range(0-10) there are 2*2*2 = 8 possibilities. But numbers possible (0-10) = 11. Therefore some numbers have the same color coding. But that leads to confusion.

2) 0 ( gr,gr,gr)and 3 ( gr ,red,gr) meaning if I jump 3 numbers there's a new color which comes in the mid position This agrees with 21 ( bl,red,gr) 23(bl,bl,gr) and another thing is clear that the new color is placed over the previous color. Meaning the blue that is introduced in the last tile of 23 ( bl,red,bl) simply sits above the green tile of 21 and it simply jumps one step left in 24(bl,bl,gr) revealing the gr that lies under it. But that leads to confusion what would be 22?

• I am sorry it's from a previous year exam paper which I am appearing. They always ask one question of this type. Are you suggesting I should also upload the main question paper as a reference? – Ritwik Bhattacharyya Jun 17 '19 at 14:53
• The URL of where the exam comes from is ideal. If it’s not online, the title and year of the exam and whose exam it is. Basically, enough to adequately disclose and attribute the original source. – Rubio Jun 17 '19 at 16:27
• It is an online exam but here's the link uceed.iitb.ac.in/downloads/UCEED.2019.Question.Paper.pdf – Ritwik Bhattacharyya Jun 17 '19 at 18:57
• Next time you can just edit that information into your question post. I’ve done that for you now. – Rubio Jun 19 '19 at 12:49
