    4 lit of milk was taken and 4 lit of water added.that means 4/40=1/10 part of milk was taken from mixture. so 9/10 part of milk remained.this continued for two more times. therefore we can do it as 40*(9/10)*(9/10)*(9/10)=29.16

My doubt is that when both the differences come out to be 0.8 and 0.8 how can we take their ratio? As it will come out to be 1:1. Please let me know what has to be done in sums like these where the differences come out to be equal.

      It is wrong. Check the video of mixture by Dear Sir channel. It is in 2 parts, check out 2nd part. The first question is exactly like this but with different numbers. And they teach much easy and smaller formula for these type of question. And by using that formula you will realise the answer of 5th question here is wrong.

    Another way to solve Qn(10) : (hard)
    consider 1 liter of all the type ;
    let k1 : k2 be the amount of food mixed (ratio)
    for k1 liter/kg type 1 food, amount of sugar k1x(sugar per liter of type1)
    ie. k1x2/13 similarly salt - k1x 11/13
    similarly for food 2
    so.
    Amount of sugar in
    k1(2/13 +11/13) +k2(5/26 +21/26) = 7/39 + 32/39 (per litre)
    equate sugar(left)---> sugar(right)
    (11/13)k1 +(21/26)k2=32/39
    similarly salt(left)---> salt(rgt)
    k1(2/13) +k2 (5/26) = 7/39
    solve for k1 and substitute in eqn and find k2 ....
    final ratio would be k1 : k2 ---> 13: 26 or 1: 2

    4question? 36 lt milk, so remaining 44 lt is water.
    The new ratio we want is 75:25, ie water is remains same ie 25%=44. ( here we r increasing the amount of milk only, so the water amount remains same)
    If 25%is =to 44 lt, then 75%is = to 25%*3 ie 44*3=132.
    So we already have 36lt of milk, we need to add 132-36=96litre of milk.....

    Please correct me if I am wrong. In 8th question, shouldn't the amount of mixture i.e. 90 L should remain same and only the ratio of acid and water should change. Hence, after the inversion of ratio, it will be 30:60, so 30L water should have been added.

    • @vivektanagawade8051
      @vivektanagawade8051 2 года назад

      Yes it can be possible but when they will say that amount of mixture is fixed and 90 L only . But when in question itself they say add amount of water added to mixture we can take meaning that amount of mixture is not fixed and we are supposed to add water in the preavailable mixture itself.

    Where
    x= amount of liquid contains
    y = amount of liquid removed and replaced
    n = number of process
    Now
    From the given data
    40(1-4/40)^3
    = 29.16
    That's it

    For 5 th question you can use X(1-(Y/X))^n.
    X is the initial amount
    Y is the amount removed
    n is the number of times this process is done.
    This could save so much time rather than going logically.
    40(1-4/40)^3 = 29.16 litres.
