A no n is not a prime no and 1

• multiplication of prime with itself or other prime gives non prime nos. so
  11*11=121
  11*13=143
  11*17=187
  11*19=209
  11*23=253
  11*29=319 which is not in range of 1-301 so we cant conider it
  13*13=169
  13*17=221
  13*19=247
  13*23=299
  17*17=289
  17*19=323 which is not in range of 1-301 so we cant conider it
  So total possible nos are 10 and option c

• Divisible is 2 = 150
  Divisible is 3= 100
  Divisible is 5 =60
  Divisible is 7 = 43
  The total prime number is 1 to 301 is 62
  all common number is 291
  may be ans is 10
