Solution:
Given: A five-storeyed building with floors from I to V is painted using four different colours and only one colour is used to paint a floor.
To ensure that any two consecutive floors have different colours, we need to use the given statements.
Statement 1: The middle three floors are painted in different colours.
Statement 2: The second (II) and the fourth (IV) floors are painted in different colours.
Statement 3: The first (I) and the fifth (V) floors are painted red.
Let us consider each statement one by one:
Statement 1:
This statement does not provide any information regarding the colour of the first and last floors. Hence, we cannot determine the colour of these floors based on this statement alone.
Statement 2:
This statement implies that the colours used on floors II and IV are different. Therefore, the colours used on floors I and III should be the same. Similarly, the colour used on floor V should also be different from the colours used on floors III and II. Hence, statement 2 alone is sufficient to ensure that any two consecutive floors have different colours.
Statement 3:
This statement implies that the colours used on floors I and V are the same. Therefore, the colours used on floors II, III and IV should be different from the colours used on floors I and V. However, we cannot determine the colours used on floors II, III and IV based on this statement alone. Hence, statement 3 alone is not sufficient to ensure that any two consecutive floors have different colours.
Combining Statements 2 and 3:
Using statement 2, we know that the colours used on floors II and IV are different, and the colours used on floors I and V are the same. Hence, the only possible arrangement of colours is:
- Floors I and V: Red
- Floors II and IV: Different colours
- Floor III: Any of the remaining two colours
Therefore, using statements 2 and 3 together, we can ensure that any two consecutive floors have different colours.
Hence, the correct answer is option B, i.e., only statement 3 is sufficient.

Hence, the correct answer is option B, i.e., only statement 3 is sufficient.

From statement (3), floor 1 and 5 are painted by the same colour red.
