Picking out the right answer options – Now, we have entire information in chronological order and can answer the questions as follows –
Answer to question-1 – S is diagonally opposite to R (the house with yellow colour) and the colour of S is Red, so option( 4)-Red is the correct answer.
Answer to question-2- Option-(5) –cannot be determined-should be the answer since either Q or S could be the 2nd tallest house.
Answer to question-3- Option-(2)-Since T is the tallest house which is situated opposite to S(the red coloured house and we have already determined the colours of all other houses except Blue) the colour of T is Blue(look at the table)
