In a code language, 'HELLO' is coded as 83 and 'SHELL' is coded as 79. How will 'MATCH' be coded in the same language?

The logic here involves summing the reverse alphabetical positional values of each letter (where A = 26, B = 25, ..., Z = 1). The reverse position can be calculated as $(27-\text{standard position})$.
Let's verify with 'HELLO' $\to$ 83:

* H $\to 27-8=19$
* E $\to 27-5=22$
* L $\to 27-12=15$
* L $\to 27-12=15$
* O $\to 27-15=12$

$$\text{Sum}=19+22+15+15+12=83$$

Let's check 'SHELL' $\to$ 79:

* S $\to 27-19=8$
* H $\to 27-8=19$
* E $\to 27-5=22$
* L $\to 27-12=15$
* L $\to 27-12=15$

$$\text{Sum}=8+19+22+15+15=79$$

Applying the same logic to 'MATCH':

* M $\to 27-13=14$
* A $\to 27-1=26$
* T $\to 27-20=7$
* C $\to 27-3=24$
* H $\to 27-8=19$

$$\text{Total Sum}=14+26+7+24+19=90$$

Thus, 'MATCH' will be coded as 90.
