The answer is b as when we add 12 and 8 it is 20. Then, we multiply 12 by 8 it becomes 96. So 96- 76 is 20. Then let's add 13 and 9=22. Then multiply 13 by 9 the answer is 117. Subtract 117 by 95 =22. Then add 7 and 6 it makes 13. Then multiply 7 by 6 the answer is 42. Then 42 - 13 is 29. So the answer is 29.

Let’s name the three set of numbers as Set P, Q and R. Now, first observe the numbers in Set P. If we multiply the top two numbers and then subtract the sum of them, we get the bottom number. (12 x 8) - (12 8) = 96 – 20 = 76. 76 is the bottom number. Let’s see if numbers in Set Q will also follow the same rule. (13 x 9) – (13 9) = 117 – 22 = 95. 95 is the bottom number. So, the rule is correct. That means the numbers in Set R will also follow the same rule. (7 x 6) – (7 6) = 42 – 13 = 29. 29 is the missing bottom number. Hence, the right answer is Option B.

The rea of the square is 196 sq units. Hence, the side of the square will be the square root of 196 i.e 14 units Now, from the figure, we can see that each square cell is of 7 units Hence, the side EH is of 21 units and the side EF is of 28 units. Now, the perimeter will be 2(L+B) = 49 cm.
