Numerical: missing number in figure MCQ - Practice Questions with Answers

In each branch figure, the lower number equals the square of the left upper number minus the square of the right upper number. Thus, 12² - 8² = 144 - 64 = 80, and 16² - 7² = 256 - 49 = 207. Applying the same rule to the third figure gives 25² - 21² = 625 - 441 = 184. The numbers 525, 464 and 334 do not satisfy this square-difference pattern, so they are only distractors.

The figure follows the rule: centre = top number × bottom number - left number × right number. In the first circle, 8 × 6 - 2 × 6 = 48 - 12 = 36. In the second circle, 7 × 8 - 2 × 5 = 56 - 10 = 46. Applying the same rule to the third circle gives 7 × 10 - 4 × 6 = 70 - 24 = 46. Therefore 46 fits the pattern. The other values do not satisfy the same multiplication-and-subtraction relation.
