Q1. In the following number sets, each set follows a similar pattern. Find the missing number (?): (7, 6, 35), (12, 5, 48), (9, ?, 63).
A 8 Correct
B 13
C 11
D 19
Explanation
The pattern is: bottom number = left number multiplied by one less than the right number. In the first set, 7 x (6 - 1) gives 35. In the second set, 12 x (5 - 1) gives 48. For the third set, 9 x (? - 1) must give 63, so ? - 1 = 7 and the missing number is 8. The numbers 13, 11, and 19 do not satisfy this same relation with 9 and 63.
