Find Solutions at the end of every section

Four bottles P, Q, R and S are arranged side by side. Each contains a fixed amount of soft drink measured in litres. The different soft drinks are Pepsi, Coke, Limca, and Sprite. Read the following clues carefully.
● Pepsi is between Sprite and Coke.

● Limca is not in bottle R. 
● The bottle containing 2.2 ltr of soft drinks doesn’t have Limca.
● Bottle R contains more amount than bottle P.
● The difference between the amount contained by Limca and Sprite is 0.6 litres.
● The bottle with Coke is between the bottles containing 0.6 ltr and 1 L.

Find Solutions at the end of every section

  • There are three houses on each side of the road.
  • These six houses are labeled as P, Q, R, S, T and U.
  • The houses are of different colours, namely, Red, Blue, Green, Orange, Yellow and White.
  • The houses are of different heights.
  • T, the tallest house, is exactly opposite to the Red coloured house.
  • The shortest house is exactly opposite to the Green coloured house.
  • U, the Orange coloured house, is located between P and S.
  • R, the Yellow coloured house, is exactly opposite to P.
  • Q, the Green coloured house, is exactly opposite to U.
  • P, the White coloured house, is taller than R, but shorter than S and Q.
1.What is the colour of the house diagonally opposite to the Yellow coloured house ?
  (a) White (b) Blue
 (c) Green (d) Red
2.Which is the second tallest house ?
  (a) P  (b) S
 (c) Q (d) Cannot be determined
3.What is the colour of the tallest house ?
  (a) Red (b) Blue
 (c) Green (d) Yellow

1.(D)   2.(D)  3. (B)
Step 1 
Firstly, we can easily prepare a table deciding the colour of each house.
P-White
Q-Green
R-Yellow
S-Red
T-Blue
U-Orange
Step 2
The second step is to arrange the houses on either sides of Road. In deciding the arrangement of houses information (vii) can be used first which decides two possibilities as follows.
Case 1.  P  -- U -- S
Case 2.  S  -- U -- P
Now, since, we know the colour of each houses the other information can easily be used to decide the final arrangement as below.

Possibility 1
Side 1  T  --  Q --  R
Side 2  S  --  U --  P
Possibility 2
Side 1  R  --  Q -- T
Side 2  P  --  U -- S

And last, the arrangement of houses in descending orders of their heights

T-S-Q-P-R-U

T-Q-S-P-R-U

1- (d) S (Red) is diagonally opposite to R(yellow)

2- (d) The second tallest house is either S or Q.

3- (b) T is the tallest house and its colour is Blue.
