A + B

Since, A B means

, the value of (1 1) 3:

2

1 + 1

(1 1) 3 = (

) 3

2

2 (1 1) 3 = ( ) 3

2

(1 1) 3 = 1 3

Step 2

A + B Again use, A B =

2

1 + 3 (1 1) 3 =

2

4 (1 1) 3 =

2

Therefore, (1 1) 3 = 2

Step 3 Hence, option b is the correct answer.

Step 1 The figure given in the problem has four equal partitions out of which one is missing. The 4 parts of the problem figure can be shown as -

12

34

It can be observed that part 1, 2, and 3 are identical to one another.

Step 2 According to this observation, we can infer that all the 4 parts in the problem figure should be identical and figure in option (b) is identical to part 1, 2, and 3 of the problem figure.

Hence,

is the correct answer.
