In a certain code language, ‘BACK’ is coded as ‘2325215’, ‘CAME’ is coded as ‘2125117’. What is the code for ‘GBJH’ in that code language?
Answer & explanation
Correct answer: option 4
1 2 3 4 5 6 7 8 9 10 11 12 13

26 25 24 23 22 21 20 19 18 17 16 15 14
**********************************************************
The logic is;
(place value of opposite letter - positional value of given letter)
So,
B → Y(25) - 2= 23
A → Z(26) - 1= 25
C → X(24) - 3= 21
K → P(16) - 11= 5
Similarly,
G → T(20) - 7= 13
B → Y(25) - 2= 23
J → Q(17) - 10= 7
H → S(19) - 8= 11
Thus, 1323711 is correct.
