Explanation
Solving
1. Analyze the Relationship in the First Pair (7 : 56):
The relationship follows the pattern x:x×(x+1) or x:x2+x.
-
7×(7+1)=7×8=56
-
Or: 72+7=49+7=56
2. Apply the Same Pattern to the Second Pair (9 : ?):
Using the same logic x:x×(x+1):
-
9×(9+1)=9×10=90
-
Or: 92+9=81+9=90
3. Verification:
-
Logic: Multiply the number by its immediate successor.
-
Applied: 9×10=90.
Correct Option: C) 90
