If a and b are mixed in 3:5 ration and b and c are mixed in 8:5 ration if the final mixture is 35 liters, find the amount of b?
A) 13.34 b) 15.73 c) 16.73 d) 9.45

• a:b = 3:5,
  b:c = 8:5,
  Then a:b:c = 8*3 : 8*5 : 5*5 = 24:40:25,
  so, amount of b = 35 * 40/(24+40+25) = 35*40/89=15.73

• a:b=3:5=3*8:5*8=24:40
  b:c=8:5=8*5:5*5=40:25
  therefore a:b:c=24:40:25
  now amount of b is=35*40/(24+40+25)=15.73

• a:b= 3:5 and b:c=8:5
  hence, a:b:c can be.... found by taking lcm of common factor "b"
  i.e. (5,8)=40
  hence, a:b:c= 3*8:40:5*5
  therefore... b= (40*35)/89
  = 15.73

• a : b: c
  3 : 5
  8 : 5
  
  So (8*3) : (5*8) : (5*5)
  
  24 : 40 : 25
  
  The value of b = (40/(24+40+25)) * 35
  
  Answer is b = 15.73
