In a certain code language, 'CAN' is written as '63', and 'TWO' is written as '23'. How will 'USE' be written in that language?

Let's find the numerical pattern using the alphabet positional values:
For CAN:

Forward positions: C=3,A=1,N=14⟹3+1+14=18

Opposite positions: C=24,A=26,N=13⟹24+26+13=63
This perfectly matches the code '63'.

Let's verify this logic with TWO:

Opposite positions: T→G(7),W→D(4),O→L(12)

Sum of opposite positions = 7+4+12=23
This perfectly matches the code '23'.

Now, applying the same logic for USE:

Opposite positions: U→F(6),S→H(8),E→V(22)

Sum of opposite positions = 6+8+22=36

Therefore, 'USE' will be written as 36.
