प्र: Minimum number of straight lines required to form the below figure ? 3640 0

उत्तर : 3. "14"
व्याख्या :
Answer: C) 14 Explanation: The given figure can be labelled as shown : The horizontal lines are AK, BJ, CI, DH and EG i.e. 5 in number.The vertical lines are AE, LF and KG i.e. 3 in number.The slanting lines are LC, CF, FI, LI, EK and AG i.e. 6 in number.Thus, there are 5 + 3 + 6 = 14 straight lines in the figure.

प्र: Find the minimum number of straight lines in the below figure ? 2741 0

उत्तर : 2. "19"
व्याख्या :
Answer: B) 19 Explanation: The given figure can be labelled as : Straight lines : The number of straight lines are 19 i.e. BC, CD, BD, AF, FE, AE, AB, GH, IJ, KL, DE, AG, BH, HI, GJ, IL, JK, KE and DL.

प्र: 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 ? 3177 0

उत्तर : 3. "3"
व्याख्या :
Answer: C) 3 Explanation: The given figure can be labelled as shown : 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.

व्याख्या :
Answer: D) Option 2,3 and 4 Explanation: when a cube is formed by folding the sheet shown in fig. (A), then 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

प्र: A cube is painted blue on two adjacent surfaces and black on the surfaces opposite to blue surfaces and green on the remaining faces .Now the cube is cut into 216 smaller cubes of equal size. 7190 0

उत्तर : 4. "64"
व्याख्या :
Answer: D) 64 Explanation: We know that Cubes with no surface painted can be find using x-23, where x is number of cuttings. Here x=6. ∴ 6-23=64

प्र: Find the total number of cubes in the given figure ? 2988 0

उत्तर : 1. "56"
व्याख्या :
Answer: A) 56 Explanation: (Total numbers of cubes in a line x Number of stack / tower) + ... = (6x1)+(5x2)+(4x3)+(3x4)+(5x2)+(6x1) = 6+10+12+12+10+6 = 56
