Find the one which does not belong to that group ?a)30b)27c)36d)45e)72...
3*9=27
4*9=36
5*9=45
8*9=72
so 30 options a are differ from others
Find the one which does not belong to that group ?a)30b)27c)36d)45e)72...
The numbers given are 30, 27, 36, 45, and 72. We need to identify the number that does not belong to the group.
Analysis:
To find the number that does not belong to the group, we need to look for a pattern or commonality among the numbers. Let's analyze each number and see if we can identify any patterns.
- 30: This is the first number in the list. It is divisible by both 2 and 3.
- 27: This number is divisible by 3 and is a perfect cube (3^3 = 27).
- 36: This number is a perfect square (6^2 = 36) and is divisible by both 2 and 3.
- 45: This number is divisible by 3 and 5.
- 72: This number is divisible by both 2 and 3.
Conclusion:
From the analysis, we can see that all the numbers in the group are divisible by both 2 and 3, except for 45. Therefore, the number 45 does not belong to the group.
Final Answer:
The number that does not belong to the group is 45 (option D).
