REASONING | NON VERBAL | ANALYTICAL REASONING | EXERCISE 2

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

6.
	A.   8	B.   10
	C.   11	D. 12

Ans : A. The simplest triangles are ABG, BCG, CGE, CDE, AGE and AEF i.e. 6 in number.

7.
	A.  21	B.   23
	C.   25	D.   27

Ans : B. The figure may be labelled as shown. The simplest triangles are GLK, DLJ, DJM, HMN, QRE, IRA, IPA, and FPO i.e. 8 in number. Thus there are 8 + 10 + 5 + 2 + 1 + 1 = 27 triangles in the figure.

8.
	A.  4	B.   5
	C.   6	D.   7

Ans : B. We may label the figure as shown. The simplest triangles are ADE, BDF, DEF and EFC. i.e., 4 in figure. There is only one triangle ABC composed of four components. Thus, there are 4 + 1 = 5 triangles in the given figure.

9.
	A.   15	B.  16
	C.   16	D.   18

Ans : C. The figure may be labelled as shown. The simple triangles are ABF, BFG, BCG, CGH, GHD, GED, EFG, and AFG i.e. 8 in number. Thus there are 8 + 5 + 4  = 17 triangles in the given figure.

10.
	A.   16		B.   13
	C.  9		D.   7								Ans : A. The figure may be labelled as shown. The simple triangles are AGE, EGC, GFC, BGF, DGB and ADG i.e., 6 in number. Thus there are 6 + 3 + 6 + 1 = 16 triangles in the given figure.
