ReplyDelete2716 becoz its sum is even

ReplyDelete5321

ReplyDelete5321 bcoz all numbers are primes in this

ReplyDelete1 is not a prime number but yes 5321 is odd as it is the only series

ReplyDeleteI think it is B) 2716 because it docent have 5 in a c and d all of them have 5 but b docent.

ReplyDeleteit's dosent

Delete2176 IS THE ONLY ONE WITH NO 5

Delete2176 IS THE ONLY EVEN NUMBER

DeleteQuestion is ambigous, One can choose various property of the number to select a odd one.

ReplyDeleteFor example

(1)addition of digit is odd or even

(2)addition of digit is prime or compound number

(3)number is odd or even

(4)No. of prime factors: odd,even,prime or dissimilar

List of such property is endless and hence answer can be different

only 2716 is divisible by 11
