a/b=5/3,b/c=2/3,c/d=7/5,and a+b+c+d=1100. then what is the value of b?

• a+b+c+d=1100,
  a/b=5/3,b/c=2/3,c/d=7/5
  write a,c,d in terms of b
  a=5b/3, c=3b/2, d=5c/7=5b/14
  now
  5b/3+b+3b/2+5b/14=1100
  by solving above b=210 ans.

• a:b=5:3
  b:c=2:3
  c:d=7:5 which implies
  a:b:c:d=70:42:63:45
  a+b+c+d=1100
  70x+42x+63x+45x=1100
  220x=1100
  x=5
  we can get b=210

• a/b=5/3 b/c=2/3 c/d=7/5
  a=(5/3)b b=(2/3)c c=(7/5)d
  a=(14/9)d b=(14/15)d c=(7/5)d
  ATQ
  a+b+c+d=1100
  =>(220/45)d=1100
  =>d=225
  b=(14/15)d
  =(14/15)*225
  =210

• 9a=15b=10c=14d..
  b=15/48*(1100)=16500/48=343.75 ans
