Next door to me livfour brothers of different heights .Their average height is 74 inches, and the difference in height among the first three men is two inches. The difference between the third and fourth men is six inches.
Can you tell how tall is each brother?

• 70, 72, 74 & 80 inches
  
  Let x, (x+2), (x+4), (x+10) inch. be the height of four brothers, then
  [x+(x+2)+(x+4)+(x+10)]/4 =74 ,On solving x=70
  So heights of four brothers are 70, 72, 74 & 80
