Question

In a pot the milk and water ratio is 3:1. If some mixture is taken and filled with same amount of water then ratio becomes 1:1. Then that part is?

Answer 1

Answer:

1/2 part is taken

Step-by-step explanation:

Let say milk = 3x

Water = x

Let say y (0≤y ≤1) Part is taken from mixture then

Milk = 3xy

water = xy

Now x water is mixed

water = xy + x

now milk : water :: 1:1

3xy : (xy +x) = 1:1

3xy = xy + x

3xy = x (y+1)

3y = y + 1

2y = 1

y = 1/2

1/2 part is taken
