      We are taking water conc from type 1 and type 2 to calculate weight ratio of type 1 and type 2. In type 1 water conc is 3/3+5= 3/8. In type 2 water conc is 7/7+3= 7/10
      In type 3, that is resultant mix we have water conc as 11/11+9 = 11/20.
      Now apply alligation map to have weight ratio of two types of liquid(which is asked in the question).

      @@siddhantdhyani4541 What he meant was we just make the denominator of the fractions equal by taking their LCM (8,10,20) i.e 40 thus the fraction becomes 15/40, 28/40 and 22/40 and solve accordingly. The result would be easiness in calculating ratio (22/40-15/40) : ( 28/40-22/40), i.e., 7:6.

    Good morning sir
    Sir I don't get how can we take 1 unit = 20 ml , we took the ratio of percentages of alcohol( 30% and 0 percent) and at 0 percent side, the ratio of alcohol's quantity is 1 (4:1) so how did we equate alcohol's quantity to 20 ml( that is of water )
    Second case - does that mean at 0 percent alcohol concentration only 20 ml water is present?? Shouldn't be water equal to total quantity of liquid like 100 ml( if we see from the answer) as no alcohol is present
    If anyone knows pls explain

      so for easy calculation just make denominator same , after multiplying by 2, 3/20 becomes 6/40 so ratio becomes

So why are we only calculating between 3:5 and 7:3 as the answer is a ratio which is between 3:5 and 7:3 without even considering the values of 11:9. Can someone please clear this doubt ?

    • @vaibhavparmar3033
      @vaibhavparmar3033 7 месяцев назад +1

      In the mixture, we take the concentration volume of only one of the liquids. Sir had taken water but you can take alcohol also. In the alcohol concentration case, Type 1 would have 5/8 or 62.5% alcohol mixed with Type 2's 3/10 or 30% alcohol which results in the mixture containing 9/20 or 45% alcohol. The distance ratio would be 17.5(62.5-45):15(45-30) which would be simplified to 7:6. This 7:6 ratio is the ratio of distance. Its inverse is 6:7 which is the ratio of the weights. (Here, weights mean the respective volumes of both the mixtures and distance refers to the difference between the %age of the concentration of any one solution(water or alcohol) in Type 1 and Type 2 with the %age of the same solution in the resultant mixture).

      15 is the average whereas 24 is the weighted average, here we are dealing with the latter one hence it is 24

      If mixing was in 1:1 ratio...then the average would have been 15. But we know here that the average is 24% and we are trying to find out in what ratio both of these solutions have to be mixed so that we get the average (hence called weighted average ) as 24%

      First he took alcohol in consideration, that means we are only considering alcohol and not water, since type 2 liquid was pure water, it is obvious that pure water doesn't contains alcohol, so alcohol will be takes as 0%, and water 100%.

      Let x ml be the total quantity of the solution
      Then 70% of x = quantity of water-----
      Next
      When 20 ml is added to x,
      76% of (x+20) = quantity of water------Ⓡ
      shouldnt we be able to find x by equating © and ® But on doing so the answer I'm getting is negative.

      New water and alcohol conc is 24/76, that would be 6/19. Now when we take 3x/7x+20 = 6/19, the new eq would be 19*3x = 6*7x + 6*20.
