 Rabish Kumar said: (Sun, Jan 2, 2011 10:37:50 AM) Sum of digits of each number is an even number except 751.

 Sundar said: (Thu, Dec 8, 2011 10:33:32 AM) 1st digit = 2nd digit + 3rd digit. 3rd digit = 1st digit - 2nd digit.

 Sonutalwani said: (Fri, Jun 29, 2012 01:54:18 PM) 8+3+5=16 even. 7+3+4=14 even. 6+4+2=12 even. 7+5+1=13 odd. 8+5+3=16 even. 9+8+1=18 even. 5+3+2=10 even. 751 is answer.

 Sonutalwani said: (Fri, Jun 29, 2012 02:02:06 PM) 8 - 5 = 3 835. 7 - 4 = 3 734. 6 - 2 = 4 642. 7 - 1 = 6 751. It is wrong answer. 8 - 3 = 5 853. 9 - 1 = 8 981. 5 - 2 = 3 532.

 Ramya Devi said: (Tue, Jul 10, 2012 08:51:39 PM) In each number except 751, the sum of 2nd digit and 3rd digit is the first one.

 Tarun said: (Thu, Dec 20, 2012 07:17:18 PM) This one is more easy 3+5=8 of 835 3+4=7 of 734 4+2=6 of 642 5+1=6 of 751 This is wrong because we got the result of addition as 6 instead of 7. 5+3=8 of 853 8+1=9 of 981 3+2=5 of 532
