SNAP 2011 Question Paper

Let us solve the problem by eliminating the options.
G: People are rewarded
C: if people are rewarded then they will not change their lifestyle.
F: Unless people change their lifestyle, temperature rises This can also be put In the following manner.
If people do not change their lifestyle then temperature rises.
This is an example of binary logic - If not A then B which can also be expressed as if not B then 'A'.
Thus if the temperature doesn't rise then people change their lifestyle.
Here, accordingtoG and C, people do not change their lifestyle and so temperature rises.
D: If temperature rises, then water level in the coastal area rises.
H: Water level In the coastal area doesn't rise.
Here, D is in accordance with G, C and F but H is not So option (A) is incorrect.
B: People change their lifestyle only if they are rewarded.
This means that if people have changed their lifestyle then they have been rewarded.
Note that if people are rewarded, they may or may not have changed their lifestyle.
G: People are rewarded.
From B and G. we don't know whether people have changed their lifestyle or not.
F: Unless the people change their lifestyle, temperature rises.
This can also be put as - If the people don't change their lifestyle then temperature rises
But

as we don't know whether people have changed their lifestyle or not,

v/e cannot conclude whether temperature has risen or not.
D: if temperature rises, then water level in the coastal area rises.
H: Water level in the coastal area doesn't rise.
As we don’t know whether temperature has risen or not, H cannot be concluded using D.
Hence, option (B) is also incorrect.

In option 2, statement A says- If Kumar sings then the audiences sleep.
Out

of the other 4 statements C, F,G and H, none of the statements mention

anything about sleep and hence option (B) is incorrect.
If option (B) is incorrect, option (D) is also incorrect as it mentions both (B) and (C).
C: Unless audience does not dance, the concert will be successful.
This can also be put as - If the audience dance, the concert will be successful.
F: Kumar sings, only if Vina dances.
This means that - If Kumar has sung, then Vina has danced.
But if Vina has danced, Kumar may or may not have sung.
B: if Kumar sings, then the audience dances.
We

don't know whether Kumar has sung or not and so we don't know whether

the audience have danced or not. Hence we cannot conclude that the

concert is successful as given in statement H.
So option (A) is also logically incorrect.
E: if Vina dances, then Kumar sings.
G: Vina dances.
Thus from these two statements v/e know that Kumar sings.
B: If Kumar sings, then audiences dance.
Thus audiences have danced.
C: Unless audience does not dance, the concert will be successful.
This can also be put as - If the audience dance, the concert will be successful.
Thus the concert is successful as mentioned in statement H.

From the statement of A, we cannot state any information about C. Similarly B and C are also providing partial details. We can find out that Dis the grandfather and A is the grandson, and CB are the couple, thus statement B is a complete truth. 

We are able to set the relationship.

Option D

From the statement of A, we cannot state any information about C. Similarly B and C are also providing partial details. We can find out that Dis the grandfather and A is the grandson, and CB are the couple, thus statement B is a complete truth.

We are able to set the relationship.

Option C

From the statement of A, we cannot state any information about C. Similarly B and C are also providing partial details. We can find out that Dis the grandfather and A is the grandson, and CB are the couple, thus statement B is a complete truth.

We are able to set the relationship.

Both the statements of B are false.

Option D

Three faces are painted as given in the figure.

Total number of cubes= 343

Total number of painted cubes=7x7+7x6+6x6=49+42+36=127

Number of cubes which are colourless =  343-127=216

Option D

Three faces are painted as given in the figure.

Total number of cubes= 343

The number of cubes with only one color on them: Blue= 6x6

Green= 6x6

Red=6x6

=3x36

=108

Option A

Three faces are painted as given in the figure.

Total number of cubes= 343

Faces with three sides painted =1
Answer= 343-1=342

Option B

We can draw the following diagram for its initial movement:

To return to its original position it can move along the path II, mentioned above.

Option B is correct.

We can draw the following diagram for its initial movement:

Further, it moves  4 km east and 1 km north.
