The ans is -20.
Solution:
A-1
B-2
C-3 D-4 …like wise till Z-26.
ELECTRICITY-5+12+5+3+20+18+9+3+9+20+25==129
GAS-7+1+9==27
ELECTRICITY-GAS=129-27-(Minus 2)=100
so
JACK-JILL=(10+1+3+11-(10+9+12+12)-(minus(2))==(-20)
no of unique character in 1st word are 7
no of unique character in 2nd word are 3
diff is 4 assigned to 100
similarly forjack and jill diff is 1 so 1/4 th of 100 is 25
