Odd Numeral Group: Explanation
Odd or Even
To determine whether a numeral group is odd or even, we need to look at the last digit of each number in the group. If the last digit is an odd number (1, 3, 5, 7, 9), then the entire group is considered odd. If the last digit is an even number (0, 2, 4, 6, 8), then the entire group is considered even.
Explanation of Options
a) 1315: The last digit is 5, which is an odd number, so this group is odd.
b) 2057: The last digit is 7, which is an odd number, so this group is odd.
c) 3216: The last digit is 6, which is an even number, so this group is even.
d) 5317: The last digit is 7, which is an odd number, so this group is odd.
Conclusion
Based on the explanation above, we can determine that the odd numeral group is option 'D' (5317) because all the other options have an even last digit.
