(viii) R, the Yellow coloured house, is exactly opposite to P.
(ix) Q, the Green coloured house, is exactly opposite to U.

How to analyse the given information
According to the given statements following information is available and can be drawn as follows
Category, Analysis-(1), Analysis-(2)
Shortest, U (Orange), U (Orange)
Taller than U (5th), R (Yellow), R (Yellow)
Taller than R (4th), P (white), P (white)
Taller than P (3rd), S (Red), Q (Green)
Taller than S (in A-1) and taller than Q (in A-2), Q (Green), S (Red)
The Tallest (as given), T (Blue), T (Blue)
1. T is therefore opposite to S and the colour of S is Red, while colour of P is white, so colour of T is blue.
2. U will be the shortest house situated opposite the green coloured house Q
3. The order of the houses in ascending order is clear as per the table
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)
