REASONING | NON VERBAL | CUBES AND DICE | EXERCISE 1

DIRECTIONS : Count the number of cubes in each of the following figures.

1.	Count the number of Cubes in each of the following figures :
	A.   100	B.   105
	C.   111	D.   121

Ans : C. In figure, there are 19 columns containing 4 cubes each, 9 columns containing 3 cubes each and 4 columns containing 1 cube each. Therefore Total number of cubes = (19×4) + ( 9×3) + (4 ×1) = 76 + 27 + 8 = 111.

2.	Count the number of Cubes in each of the following figures :
	A.   8	B.   9
	C.   12	D.   15

Ans : D. Clearly, there are 4 columns containing 1 cube each, 4 columns containing 2 cubes each and 1 column containing 3 cubes. Hence, there are (4×1) + (4×2) + (1×3) = 4 + 8 + 3 = 15 cubes in the given figure.

3.	Count the number of Cubes in each of the following figures :
	A.   81	B.   87
	C.   88	D.   89

Ans : D. In figure, there are 23 columns containing 3 cubes each, 8 columns containing 2 cubes each and 4 columns containing 1 cube each. Therefore Total number of cubes = (23×3) + ( 8×2) + (4 ×1) = 69 + 16 + 4 = 89.

4.	Count the number of Cubes in each of the following figures :
	A.   28	B.  36
	C.   40	D.   42

Ans : C. In figure, there are 4 columns containing 3 cubes each, 12 columns containing 2 cubes each and 4 columns containing 1 cube each. Therefore Total number of cubes = (4×3) + ( 12×2) + (4 ×1) = 12 + 24 + 4 = 40.

5.	Count the number of Cubes in each of the following figures :
	A.57	B.58
	C.60	D.62	Ans : B. In the  figure, there are 4 columns containing 5 cubes each and 38 columns containing 1 cubes each. Therefore Total number of cubes = (4×5) + ( 38×1) = 20 + 38 = 58.
