A1

B9

C3

D4

Answer:

A. 1

Read Explanation:

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

Select the set in which the numbers are related in the same way as are the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
