If N be a number then which among the following is predecessor of N+2?...
Explanation:
To find the predecessor of a number N, we need to determine the number that comes before N.
We are given the options:
a) N 3
b) N 1
c) N
d) N - 1
e) None of these
Explanation of each option:
a) N 3: This option suggests adding 3 to the number N. However, we are looking for the number that comes before N, so this option is incorrect.
b) N 1: This option suggests subtracting 1 from the number N. Since we are looking for the predecessor, which is the number that comes before N, this option is the correct answer.
c) N: This option suggests that N itself is the predecessor, but the predecessor is the number that comes before N, so this option is incorrect.
d) N - 1: This option also suggests subtracting 1 from the number N, which is the correct approach to finding the predecessor. Therefore, this option is also correct.
e) None of these: This option implies that none of the given options are correct. However, as explained above, option b) (N 1) and option d) (N - 1) are both correct answers.
Conclusion:
The correct answer is option b) N 1 because subtracting 1 from the number N gives us the predecessor, which is the number that comes before N. Option d) N - 1 is also correct, as it suggests the same approach.
