Q1. Choose the odd one out from the given options.
A (11, 143)
B (7, 67) Correct
C (5, 35)
D (13, 195)
Explanation
In the consistent pairs, the second number is obtained by multiplying the first number by the next odd number. Thus 11 is multiplied by 13 to give 143, 5 is multiplied by 7 to give 35, and 13 is multiplied by 15 to give 195. For 7, the same pattern would require 7 multiplied by 9, giving 63. The printed pair gives 67 instead, so it does not follow the common rule. Therefore, the pair (7, 67) is the odd one out.
