Following a certain logic, if 36 is related to 9 and 100 is related to 49, to which of the following is 225 related?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3, i.e., 144.
36 is related to 9
(6)2 = 36
6 - 3 = 3, (3)2 = 9
100 is related to 49
(10)2 = 100
10 - 3 = 7, (7)2 = 49
Similarly, 225 is related to 144
(15)2 = 225
15 - 3 = 12, (12)2 = 144
