Which of the following is two more than the square of an odd integer?  Pick:
A) 14,173
B) 14,361
C) 14,643
D) 14,737
E) 14,981
one of the given options should be a square if 2 is subtracted from it.   the options would be   (A) 14,171   (B) 14,359   (C) 14,641   (D) 14,735   (E) 14,979   We can solve this question with many approaches. Here are the 2 easiest methods.   Method 1:-   If a square has odd unit's digit, then it's ten's digit will always be even.   Only 14,641 satisfies this condition.   Method 2:-   If you know about palindromic numbers,   then you can clearly see that 14,641 is a palindromic square.   Answer:- 14,643
