Question

In a mixture ratio of spirit and water is 5 ratio 3 when 15 litre mixture is taken out and replaced by 20 litre water quantity of heat and water become equal find the initial quantity of mixture

Answer 1

Answer:

95 Litre

Step-by-step explanation:

Let say Spirit = 5S  Litre

then Water = 3S   Litre

Total Mixture = 8S litre

15 litre mixture is taken out

=> Spirit Taken out  =  (5S/8S)*15 = 75/8 Litre

Water Taken out = (3S/8S) * 15 = 45/8 Litre

20 Litre water is added

Spirit = 5S - 75/8

Water = 3S - 45/8 + 20

5S - 75/8  = 3S - 45/8 + 20

=> 2S = 30/8 + 20

=> S = 15/8 + 10

=> S = 95/8

=> 8S = 95

initial quantity of mixture = 95 Litre
