I think that the OA is wrong in this question. What do you think?
Is the two-digit prime number \(p\) equal to 17 ?
(1) \(p^2\) is greater than 250
(2) \(p = n^2 + 1\), where n is an integer.
The OA is B. The OE mentions that the only two-digit prime that is one larger than a square is 17. But, what about 37?
37 is a prime number, and \(37 = 6^2 +1\).
By the way, is there a faster way to solve this question than picking numbers?
