The average of 9 numbers is 35 the average of first 5 numbers is 32 and that of last 3 numbers is 37 find the 6th number?

• sum = average*no of numbers
  sum of 9 numbers=9*35=315
  sum of first 5 numbers = 5*32=160
  sum of last 3 numbers = 3*37 = 111
  6th no = 315-(160+111)=315-271=44

• 35*9=315
  32*5=160
  37*3=111
  315-(160+111)
  =315-271=44.

• (x1+x2+.....+x9)/9=35
  =>(x1+x2+..+x6+...+x9)=315..........(1)
  (X1+X2+.....+x5)/5=32
  =>(x1+x2+...+x5)=160.................(2)
  (x7+x8+x9)/3=37
  =>(x7+x8+x9)=111.....................(3)
  put value of equation 2 and 3 in equation 1
  we get,x6=44 Ans.
  thanks :)
