Correct Answer - Option 1 : Only Conclusion - I
Statements :
All numbers are divisible by 2.
All numbers are divisible by 3.
Conclusions:
1) All numbers are divisible by 6. (True)
Least common multiple (LCM) of 2 and 3 is 6. Therefore, if the numbers are divisible by 2 and 3 both then the numbers are definitely divisible by 6.
2) All numbers are divisible by 4. (False)
All numbers that are divisible by 2 and 3 may not be divisible by 4. For example, 6 is divisible by 2 and 3 but not divisible by 4.
Hence, Only Conclusion - I follows.
