In a certain code language, 'SIGNAL' is coded as 673425, and 'SLIDE' is coded as 65719. How will 'IDEAL' be coded in that language?
- A71925
- B59751
- C97521
- D97215
Solution & Step-by-step Explanation
Let's check for direct character-to-digit substitution by comparing the common letters between the words:
From SIGNAL → 673425:
S = 6, I = 7, G = 3, N = 4, A = 2, L = 5
From SLIDE → 65719:
S = 6, L = 5, I = 7, D = 1, E = 9
Notice that the codes for common letters match perfectly (S=6,I=7,L=5). This confirms a direct letter-to-digit substitution cipher.
Now, let's find the digits for IDEAL:
I = 7
D = 1
E = 9
A = 2
L = 5
Combining these codes in order gives 71925.
