the avg of 5 consecutive odd numbers is 84% of highest numbers.what is the sum of first of first two numbers

  Let the five consecutive odd numbers be x, x+2, x+4, x+6, x+8 then
  Its average=(x+ x+2 + x+4 + x+6 + x+8)/5 = *=(x+8)*84/100
  => (5x +20)/5 = (21x+168)/25
  => 25x+100= 21x+168
  => 4x= 68 or x=17
  So the numbers are 17, 19, 21, 23, 25 and sum 17+19= 36

  explanation (5x + 20)/5 = .84*(x+8)
  on solving x = 17
  so sum of first two numbers - 17 + 19 = 36

• for a consecutive series with odd number of units the average of units is the midde number....
  so in a series of x,x+2,x+4,x+6,x+8.... the average is x+4.....
  from the question average of number =84%highest number
  so x+4=0.84*(x+8) ---->0.16x=2.72 ----->x=17
  number are 17,19,21,23,25
  sum of first two numbers=17+19=36
