IT WILL BE- B BECAUSE IF ANY NUMBER IS MULTIPLE OF 2 AND 3 IT IS ALSO MULTIPLE OF 6 FOR EXAMPLE-2 X 3= 6 3 X 2=6 6 X 1 =6 SO THE NUMBER WHICH IS THE MULTIPLE OF 2 AND 3 WILL ALSO BE THE MULTIPLE OF 6

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.

Letâ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 â 20 = 76. 76 is the bottom number. Letâs see if numbers in Set Q will also follow the same rule. (13 x 9) â (13 9) = 117 â 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) â (7 6) = 42 â 13 = 29. 29 is the missing bottom number. Hence, the right answer is Option B.
