if the average of 6 numbers is 32.if each of the first three numbers is increased by 2 and each of the remaining three numbers is decreased by 4,then the new average is what..?

• average of 6 number is 32.
  So total of 6 number is 32*6=192
  now add 2 three times and subtract 4 three times because it is added to the number and subtracted from the number
  
  so
  192+6-12=186
  divide 186 by 6 to get new average
  i.e
  186/6= 31
