Question

In a certain code language, 'REST' is coded as '3149' and 'SEAT' is coded as '4398'. How is 'R' coded in the given language?

• A. 1
• B. 9
• C. 3
• D. 4

Answer 1

Answer:

A. 1

Compare the two words:

REST → 3149
SEAT → 4398

Common letters in both words: S, E, T

From REST (3149) and SEAT (4398):

• The common digits are 3, 4, 9 → these must represent S, E, T (in some order)

Now, the remaining digit in each:

• In REST → 1

• In SEAT → 8

The only letter present in REST but not in SEAT is R
So R = 1

Final Answer:

1
