Question
37 is related to 16 following certain logic. Following
the same logic, 44 is related to 23. Which of the following number is related to 56, following the same logic?Solution
The logic followed here is as follows: For '37 is related to 16': = (16 + 21) = 37 For '44 is related to 23': = (23 + 21) = 44 Similarly, for the number related to ‘56': = (56 + 21) = 77 So, '77' is related to '56'.
