If Yp and Yx are the two prime number and the difference between the two prime number is less than 12 and there product is 11227.then how many prime number exists between these two prime no
a) 0 b) 1 c) 2 d)3

• (11227)^1/2=is within 105-106.
  take prime numbr less than 105.it's 103.now 11227/103=109.the only prime within that renge is 107

• ans (b)1
  Yp=109,Xp=103,
  103*109=11227
  here is only one prime no b/w 103 and 109 is 107

• ans=1
  
  
  unit digit is 7 so there are 2 combinations 9*3 or 7*1
  so try frm this purpose (11227)^1/2=is within 105 to 106
  so try nearest to them then frist posiblity is 101*107 !=11227
  but 103*109=11227
  so there is only 1 prime no. between them which is 107
