If in a coding system, FIXED is coded as 86 and COMPANY is coded as 101, then how will INTERIM be coded in the same coding system ?

**********************************************************

The pattern here is;

FIXED as 86,

(opposite of FIXED is URCVW)

Now, sum of positional value of URCVW and -1

21+18+3+22+23 -1

86

And,

COMPANY as 101,

(opposite of COMPANY is XLNKZMB)

Now, sum of positional value of XLNKZMB and -1

24+12+14+11+26+13+2 -1

101

Similarly,

INTERIM  as ....?,

(opposite of INTERIM is RMGVIRN)

Now, sum of positional value of RMGVIRN and -1

18+13+7+22+9+18+14 -1

100
