Mukesh said: (Feb 25, 2011)  
There is another method to solve this which is that the sum of all the digits of a number except 427 is even. 
Girija said: (Sep 12, 2011)  
Answer may also 671. Since its not an even number. 
Kiran said: (Oct 6, 2011)  
Adding each individual numbers we get even number except 427 it is odd. 3+9+6=18 so on. 
Sankar said: (Jan 7, 2012)  
The options A,C, D are the even numbers because option A) 396 3+9+6=18 C) 671 6+7+1=14 D) 264 2+6+4=12. The remaining is option B)427 4+2+7=13 that odd number. So the answer is B.

Out of the four options 427 is not divisible by 3. 
Gopal said: (Mar 1, 2012)  
All the numbers except 427 are multiple of 11. 
Sonutalwani said: (Jun 27, 2012)  
3+9+6=18 even. 4+6+2=12 even. 5+7+2=14 even. 4+2+7=13 odd. 
Swetha said: (Jul 11, 2012)  
Except 427 every number is divisible by 11. 
Ashish said: (Jul 30, 2013)  
Just check the divisibility rule of 2. All digits are divisible by 2 except 671. So why not 671? 
Suresh said: (Aug 19, 2013)  
May be @Swetha and @Gopal is right. But @Ashish's answer is not perfect. Because 427 is not divisible by 2. I can't accept the answer given by the internet.

Pavan said: (Jan 27, 2014)  
Sum of first and last number equal to the middle number except 427. 
Sravya said: (Jun 3, 2014)  
Sum of all digits are even except 427. 4+2+7=13 odd num. So 427 is odd one. From the given series. 
Aghil said: (Jun 18, 2014)  
The number in the middle or ten's place is the sum of the other two digits. 572 = 5+2 = 7. 462 = 4+2 = 6 so on.. But 427 is not applicable. So it is odd. 
Krishna said: (Jul 19, 2014)  
Sum digit is even number in the given option except 427. 
Sony said: (Aug 11, 2014)  
Subtract second integer from first integer we get sum. For ex: 572 = 75 = 2; 462 = 64 = 2; Like this. 
Pavan said: (Nov 3, 2014)  
Why not 671 as the other all is evens? 
Arnab said: (Dec 12, 2014)  
427 is not divided by 11. Other numbers are divided by 11. 
D.Nandhini said: (Mar 2, 2015)  
Answer may also 396 because there is no number having 9 in the middle. 
Shubhankar Shukla said: (Jun 8, 2015)  
The sum of all the numbers is divisible by 2 except 427. 
Kiran said: (Jun 10, 2015)  
Answer is B. Because 396, 3+9+6=18 671, 6+7+1=14 427, 4+2+7=13 264, 2+6+4=12 the sum of numbers are even except 427 its sum is 13. Which is odd then answer is? 
Sudheer Reddy said: (Aug 14, 2015)  
396 (93=6) the middle one minus first one we get the last one. The same procedure is done in all numbers but where as in 427 (24=2) we get negative so the answer is 427.

You giving good explanation I am learning form IndiaBix thank you so much. 
Aditya Somani said: (Apr 13, 2016)  
The answer should be D) 264. All but this number are exactly divisible by 8. 
Lakshman said: (Jun 26, 2016)  
396 = 3 + 9 + 6 = 18. 427 = 4 + 2 + 7 = 13. 671 = 6 + 7 + 1 = 14. 264 = 2 + 6 + 4 = 12. In the above 4 options only 427 is odd number so 427 is correct. 
Rinky said: (Jul 11, 2016)  
Every number except 427 is multiple of 11. 
Navadurga said: (Oct 8, 2016)  
396 = 3+9+6=18. 427 = 4+3+7=14. 671 = 6+7+1=14. 427 = 4+2+7=13. In the above options427 is give odd number by adding individual numbers so it is correct. 
Souvik Mallick said: (Jan 23, 2017)  
3 + 9 + 6 = 18 even. 4 + 6 + 2 = 12 even. 5 + 7 + 2 = 14 even. 4 + 2 + 7 = 13 odd. 
Veera said: (Apr 16, 2017)  
I agree with your method it's simple and fast. Thanks @Souvik Mallick. 
Ananya said: (Apr 22, 2017)  
All the other numbers are divisible by 11. 
Sooraj said: (Jul 7, 2017)  
Thanks @Ananya. 
Eeshan said: (Aug 10, 2017)  
Except 427 all are multiples of 11. 
Tahira said: (Aug 17, 2017)  
3+9+6=18. 4+6+2=2. 5+7+2=14. 4+2+7=13odd. 427 is the odd number. 
Prathyusha said: (Jul 10, 2018)  
3+6+9 4+2 = 6. 5+2 = 7. But 4+7 is not equal to 2. So this 427 is the correct answer. 
Mr. Paul said: (Jul 16, 2018)  
Why can't be 671? It is an odd number. 
Rohan Kanade said: (Aug 25, 2018)  
All are multiples of 11 except 427. 
Ganesh said: (Apr 20, 2019)  
Here the logic is; 3+6 = 9, 2+4 = 6, 5+2 = 7, 6+1 = 7, 2+ 4 = 6. 
Sangay said: (Sep 19, 2019)  
Thanks @Ganesh. 
Ajinkya said: (Jan 11, 2020)  
Each number is divisible by other numbers, and 427 is a prime number. 
Arijit Kumar Das said: (Apr 2, 2020)  
On the basis of odd and even 671 will be the answer. 
Chaitanya Yelgate said: (May 8, 2020)  
All except 427 are divisible by 11. 396/11=36 671/11=61. 462/11=42. 264/11=24. 572/11=52. But 427 is not divisible by 11. So, the answer is opt. (b).
