Statement 1:tonebeeze wrote:How many divisors does positive integer N have?
1. The difference between the largest and the smallest divisor of N is 21
2. N+1 has 2 divisors
OA is A
Sufficient
Please note that the largest divisor is the number itself (and smallest is 1), so we know the number.
Statement 2:
Insufficient
you can check with different values of n, that thsi will give different results.
Hence, A
