Given the question:

If FRAUD = 50, CROOK = 62, CHEAT = 37 then what is the code for CHINA = ?

The solution is:

Let's convert each letter into a number in the words like A is 1, B is 2, C is 3 and so on until Z is 26.

Then, add the numbers all together in the word.

For example, FRAUD = 6+18+1+21+4 = 50.

Following this, CHINA = 3+8+9+14+1 = **35**.
