Question

Write two pairs of twin primes between $20$ and $50.$

• A. $16$ and $26,19$ and $29$
  
• B. $29$ and $31,41$ and $43$
• C. $11$ and $21,61$ and $71$
  
• D. $15$ and $17,37$ and $39$
  

Answer 1

The correct option is B $29$ and $31,41$ and $43$

A twin prime is a set of prime numbers that must be either $2$ less or $2$ more than another prime number. Example $5$ and $7,11$ and $13.$
$29$ and $31,41$ and $43$ are two pairs of twin primes between $20$ and $50.$
