SolutionFirst, we take the numbers in P. If we add the left number and the right number, we get – 21 24 = 45 If we add the top number and the bottom number, we get – 8 9 = 17 Now, if we subtract these two numbers – 45 – 17 = 28 – we get the middle number. Let’s check in numbers in R has the same pattern. If we add the left number and the right number, we get – 29 35 = 64 If we add the top number and the bottom number, we get – 9 10 = 19 Now, if we subtract these two numbers – 64 – 19 = 45 – we get the middle number. That means the numbers in Q will follow the same pattern. Let’s add the left and the right numbers - 23 42 = 65 Let’s add the top and the bottom numbers – 11 12 = 23. Let’s subtract these two numbers – 65 – 23 = 42 That means 42 will be the middle number in Q. Option B is the right answer.
