• A. $2400$
• B. $2491$
• C. $2450$
• D. $2241$

Answer 1

Answer: (B)

$2491$

We know that:

Smallest prime number greater than $50$ is ${}^{\prime }{53}^{\prime }$

Greatest prime number less than $50$ is ${}^{\prime }{47}^{\prime }$

Product of the above two numbers $=$ $53$ $\times$ $47$ $=$ $2491$

Therefore, product of smallest prime number greater than ${}^{\prime }{50}^{\prime }$ and the greatest prime number less than $50$ is ${}^{\prime }{2491}^{\prime }$.
