If BRASS is coded as 63516, then which of the following can be the code for SIR ?
315
None of these
536
617
631
In this, the S is repeated twice and 6 is also repeating. So, we can conclude the code for S is 6.
Now I & R left.
So the code for R will be from 351
and code for I will be any other number which should not be there in the code of BRASS.
So, the only option left for SIR is 617.
