divide 581 into three parts such that 4 times the first may be equal to 5 times the second and 7 times the third ??

• Suppose three parts are F,S,T respectively, then
  
  4F= 5S= 7T = x
  F= x/4
  S= x/5
  T= x/7
  also
  x/4 +x/5 + x/7 = 581
  x= 581*140/83 = 980
  
  F= 980/4= 245
  S= 980/5 = 196
  T= 980/7 = 140

• ans:245,196,140
  let x and y are 1st two part so,3rd part is 581-(x+y)
  4x=5y=7(581-(x+y))

• x+y+z= 581
  4x=5y=7z
  x+4/5 x+4/7 x= 581.. solving we get
  x=245,y=196,z=140
