Show answer & explanation
Correct answer: A
Explanation of the pattern:
The analogy follows a pattern where the first number in each pair is
n×(n+1), and the second number is (n+1)×(n+2)
First Pair (42 : 56):
42=6×7
56=7×8
Second Pair (110 : ?):
110=10×11
Following the pattern, the missing number should be
11×12
Calculation:
11×12=132
