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?

• make the ratio of b in both a:b and b:c as 40(lcm of 8 & 5).
  then new ratio will be 24:40(a:b) and 40:25(b:c).
  Thus a:b:c is 24:40:25
  thus 35*(40/89)=15.73

• 3:5 *8
  8:5 *5
  24;40
  40:25
  =>
  25:40:25
  therefore b is 40 * 35 /( 25+40+25)=15.7303370787

• The new compound ratio will be 24:40:25 (to get 3:5:5*5/8)
  Then b's part = 40/(24+40+25)*35 =15.73

• a:b=3:5
  b:c=8:5
  so,a:b:c=(8*3):(8*5):(5*5)=24:40:25
  now,
  given value of final mixture is 35 litre
  that means
  (24+40+25)=35
  =>89=35
  so,1=35/89
  so,40=(35/89)*40 [here 40 is the value of b ]
  solving this we get 15.73
  .......
  so the ans is 15.73
