Correct Answer: 72 : 16 : 8
Solution :
Let's check the options –
First option:
36 : 13 : 7→36 + 13 = 49; (7)
2
= 49
Second option:
16 : 9 : 5→16 + 9 = 25; (5)
2
= 25
Third option:
72 : 16 : 8→72 + 16 = 88; (8)
2
= 64
≠
88
Fourth option:
1 : 3 : 2→1 + 3 = 4; (2)
2
= 4
So, only for the third option the sum of the first two numbers is not equal to the square of the third number. Hence, the third option is correct.
