Question

a mixture contains milk and water in the ratio 5:1, on adding 5 liters of water, the ratio of milk and water becomes 5:2, what is the quantity of milk in the first mixture​

Answer 1

Solution :-

Let the quantity of milk and water be 5x and x respectively.

According to the question,

=> 5x/(x + 5) = 5/2

=> 5x × 2 = 5(x + 5)

= 10x = 5x + 25

=> 10x - 5x = 25

=> x = 25/5 = 5

Hence,

Quantity of milk = 5x = 5 × 5 = 25 litres

Answer 2

Answer=25 litres

Method-1

$(Let \: Milk \: be \: 5x) \\ </p><p>(Let \: Water \: be \: x)$

$(Water = x + 5) \\ </p><p> \frac{5x}{x + 5} = \frac{5}{2} </p><p>$

$Value \: be( x = 5)</p><p>$

$(5x = 5) \\ (5 = 25 litres)</p><p>$

Totally answer can be solved in 2 methods
