Question

In a mixture of 60L, the ratio of milk and water 2 : 1. If this ratio is to be 1 : 2, then the quantity of water to be further added is

Options

• 20 L

• 30 L

• 40 L

• 60 L

Answer 1

60 L
Explanation:

Quantity of milk = `60xx2/3L=40L`

Quantity of water = (60 - 40)L = 20
Let the quantity of water to be added further be x litres.

Then, milk : water = `(40/(20+x))`

Now, `(40/(20+x))=1/2`

⇒ 20 + x = 80 ⇒ x = 60L
