SSC CGL Model Paper 10

Concept:The odd one out is found by checking a shared property among most of the given numbers.Explanation:The given numbers are $43$, $22$, $13$, and $41$.Check whether each number is prime or composite.$43$ has only factors $1$ and $43$, so it is prime.$13$ has only factors $1$ and $13$, so it is prime.$41$ has only factors $1$ and $41$, so it is prime.$22$ has factors $1$, $2$, $11$, and $22$, so it is composite.Thus, $22$ is different from the other three numbers because they are all prime.So, the odd one out is $22$.Answer:$22$
