In a certain code language, ‘FLY’ is written as ‘38’ and ‘NUT’ is written as ‘26’. How will ‘GOD’ be written in that language?

The logic here depends on calculating the sum of the reverse alphabetical positional values of each letter (where $Z=1,Y=2,\dots ,A=26$, calculated as $27-\text{original position}$).
* For 'FLY':
* $\text{F}\to 27-6=21$
* $\text{L}\to 27-12=15$
* $\text{Y}\to 27-25=2$
* $$\text{Sum}=21+15+2=38$$

* For 'NUT':
* $\text{N}\to 27-14=13$
* $\text{U}\to 27-21=6$
* $\text{T}\to 27-20=7$
* $$\text{Sum}=13+6+7=26$$

Applying the identical reverse value logic for 'GOD':

* $\text{G}\to 27-7=20$
* $\text{O}\to 27-15=12$
* $\text{D}\to 27-4=23$
* $$\text{Sum}=20+12+23=55$$

Therefore, 'GOD' will be written as 55.
