In a certain code language, 'CASTER' is coded as '32619759'. How will 'FRIDGE' be coded in that language?

Let's look at the positional values or reverse values for CASTER:
C→3 (Forward positional value)

A→26 (Reverse positional value: 27−1=26)

S→19 (Forward positional value)

T→7 (Reverse positional value: 27−20=7)

E→5 (Forward positional value)

R→9 (Reverse positional value: 27−18=9)

The pattern is alternating between Forward positional values and Reverse positional values.
Let's string them together: 3⋅26⋅19⋅7⋅5⋅9=32619759. This matches the given code.

Let's apply this exact pattern to FRIDGE:

F (Forward position) =6

R (Reverse position) =27−18=9

I (Forward position) =9

D (Reverse position) =27−4=23

G (Forward position) =7

E (Reverse position) =27−5=22

Combining these values sequentially: 69923722.
