1. Answer:

   14 Either the question is wrong or the given options are wrong

   Step-by-step explanation:

   I think you missed to mention the x in question

   I’m considering the numbers as follows

   6,9,4,2,6,15,x

   Mean of the 7 numbers is 8

   Therefore sum of 7 numbers is 7×8=56

   That means 6+9+4+2+6+15+x=56

   42+x=56

   Therefore x=14

2. Answer:

   ( 6 + 9 + 4 + 2 + 6 + 15 + x ) / 7 = 8

   ( 42 + x) /7 = 8

   x = (8 x 7) -42

   x = 56 – 42

   x = 14
