In a certain code language, SAD is coded as 48 and DOG is coded as 52. What is the code for HIT in that language?

Let's first look at the positional values of letters in the standard alphabetical order (A=1,B=2,…,Z=26).
For SAD:

S=19, A=1, D=4

Sum of positional values = 19+1+4=24

Given code is 48, which is 24×2=48.

For DOG:

D=4, O=15, G=7

Sum of positional values = 4+15+7=26

Given code is 52, which is 26×2=52.

The pattern is: Code=(Sum of positional values)×2.

Applying this pattern to HIT:

H=8, I=9, T=20

Sum of positional values = 8+9+20=37

Code=37×2=74.

Thus, HIT is coded as 74.
