Question

the volume of milk in one Container is thrice that in another. if we take out 10 liters of milk from first and add to the other, the volume of milk in each Container becomes equal. find the volume of milk in each Container.
answer is 1)30
2)10​

Answer 1

Answer:

Final concentration = Initial concentration

(1− InitialReplaced )

=100(1− 100 10 )=100× 100 90 × 100 90 × 100 90 × 10090

= 65.61 litres

Answer 2

Answer:

Let the volume of milk in on container be x and the other y

According to the problem,

y = 3x --(i)

y - 10 = x --(ii)

Putting the value of x from (ii) in equation (1),

y= 3(y-10)

y= 3y - 30

2y = 30

y = 15

Putting the value of y in (i)

15 = 3x

x = 5

Therefore first container has 5 litres of milk and the second has 15 litres of milk
