In a certain code language, 'ASK' is written as '100', and 'BAG' is written as '142'. How will 'DIE' be written in that language?

Let's find the logic by looking at the positional values of the letters in the English alphabet:
For 'ASK':

A = 1, S = 19, K = 11

Sum of positions = 1+19+11=31

Opposite positional values: A → 26, S → 8, K → 16

Sum of opposite positions = 26+8+16=50

Notice that 50×2=100.

Let's check this logic with 'BAG':

Opposite positional values: B → 25, A → 26, G → 20

Sum of opposite positions = 25+26+20=71

Multiply by 2: 71×2=142.
The logic is verified: (Sum of opposite positional values) × 2.

Now apply this logic to 'DIE':

Opposite letters: D → W (23), I → R (18), E → V (22)

Sum of opposite positions = 23+18+22=63

Multiply by 2: 63×2=126.
