# How to solve this coding decoding puzzle? [closed]

If in a certain code language CMWAX is coded as 51525525. Then what is the code for CIPKZ?

Any help will be highly appreciated. Thank you very much.

• should it be 51525326 instead?? – Omega Krypton Jul 22 '19 at 11:18
• I also thought that. But it was not given. Do you think it in the way that the number of position + 2? – math maniac. Jul 22 '19 at 11:21

I guess it would be

$$510201530$$

Reasoning

Convert the string to numbers corresponding to the letter positions in the alphabet $$CMWAX \rightarrow 3,13,23,1,24$$
Take the next multiples of $$5$$ after each of these numbers
$$3,13,23,1,24 \rightarrow 5,15,25,5,25$$
Concatenate the result
$$5,15,25,5,25 \rightarrow 51525525$$

For the example in question, we have
$$CIPKZ \rightarrow 3,9,16,11,26 \rightarrow 5,10,20,15,30 \rightarrow 510201530$$
