      (A)

1111484628875.png image

A) Option 1,2 and 3 B) Option 1,3 and 4
C) Option 2 and 3 D) Option 2,3 and 4
 
Answer & Explanation Answer: B) Option 1,3 and 4

Explanation:

When the sheet in fig. (A) is folded, then one of the faces of the cube formed will be of the form 14-11484629084.png image  and this face will lie opposite the face bearing a square. Also, one of the blank faces lies opposite another blank face and the third blank face lies opposite the face bearing an '=' sign. Clearly, all the three blank faces cannot appear adjacent to each other. So, the cube shown in fig. (2) which has all the three blank faces adjacent to each other cannot be formed. Hence, only the cubes shown in figures A, C and D can be formed.

A) Option 1,2 and 3 B) Option 1,2 and 4
C) Option 2 and 3 D) Option 2,3 and 4
 
Answer & Explanation Answer: D) Option 2,3 and 4

Explanation:

when a cube is formed by folding the sheet shown in fig. (A), then 22-11484628706.png image  is one of the faces of the cube and this face lies opposite to a blank face. Also, a face bearing a square lies opposite to another blank face. The remaining two blank faces lie opposite to each other. Clearly, in the cube shown in fig. (1), the face consisting of the four symbols is not the same as that formed (as shown above). Hence, the cube in fig. (1) cannot be formed

Q:

What is the minimum number of colour pencils required to fill the spaces in the below figure with no two adjacent spaces have the same colour ?

            631484547933.png image

A) 5 B) 2
C) 3 D) 6
 
Answer & Explanation Answer: C) 3

Explanation:

The given figure can be labelled as shown :

63-11484548871.png image

The spaces P, Q and R have to be shaded by three different colours definitely (since each of these three spaces lies adjacent to the other two).
Now, in order that no two adjacent spaces be shaded by the same colour, the spaces T, U and S must be shaded with the colours of the spaces P, Q and R respectively.
Also the spaces X, V and W must be shaded with the colours of the spaces S, T and U respectively i.e. with the colours of the spaces R, P and Q respectively. Thus, minimum three colour pencils are required.
