Question

Select a number that satisfies both the given conditions:
A: It should be greater than $12$ and less than $20$.
B: It should be a composite number between two prime numbers.

• A. $14$
• B. $16$
• C. $12$
• D. $18$

Answer 1

The correct option is D $18$

The numbers greater than $12$ and less than $20$ are $13,14,15,16,17,18,$ and $19$.

• We have to find a composite number between $12$ and $20$.
• The numbers that are underlined are composite numbers: $13,14,15,16,17,18,$ and $19$

Thus, the composite number that is greater than $12,$ less than $20,$ and also lies between two prime numbers is $18$.
