next door to me live four brothers of different heights . Their average height is 74 inches, and the difference in height amongst the first three man is 2 inches. The difference between the Third and Fourth man is 6 inches .Can you tell how tall is each Brother ?

• let the hight of tallest brother be x
  x,x-2,x-4,x-10 inches
  as we know avege of their height is 74 so acc to ques
  (x+(x-2)+(x-4)+(x-10))/4 = 74
  = 296
  x=78
  78,76,74,68 are the heights from tallest

• x,x-2,x-4,x-10 inches
  x+(x-2)+(x-4)+(x-10)= 74*4 = 296
  x=78
  78,76,74,68 are the heights from tallest
