Step-by-step explanation:

r is not adjacent to s or a

Answer 2

B is adjacent to R.

• According to the question, there are five letters arranged in a row. These five letters are R, A, S, M and B. We can use the elimination method to solve this question easily.
• So, when 'O' is not a letter among the five given letters. It is eliminated.
• Now, let's write the letters according to the 4 given statements.
• The order will be 'A' 'S' 'M' 'R' and 'B' or 'B' 'R' 'M' 'S' and 'A'. (note that the position of A and S can change that is A can be ahead of 'S' or 'S' can be ahead of A.)

Hence, in all the possible cases B is always adjacent to R.
