Answer 1

Given :

A figure with some numbers

To Find :

The pattern of the numbers given in the boxes.

Solution :

Numbers which are placed in outer circle = x and y

Numbers which are placed in the center = ab

The pattern is :

(x-y) - (a-b) = 1

1. (12-8) - (6-3)

    4 - 3 = 1

2. (4-3) - (1-1)

     1 - 0 = 1

3. (9-6) - (6-4)

     3 - 2 = 1

Therefore,

4. (12-10) - (a-b) = 1

2 - (a-b) = 1

(a-b) = 2 - 1

From the given options (4-3) = 1

2 - (4-3) = 1

2 - 1 = 1

Option a) 43 is the answer.
