Question

9. A vessel contains 25 litres of a mixture of milk and
water containing 40% milk. Find the quantity (in litres)
of pure milk to be added to the vessel so that the ratio
of milk and water in the vessel becomes 1:1.
​

Answer 1

Answer:

I think it is 4 litres. .............

Answer 2

Answer:

5 litres

Step-by-step explanation:

Mixture volume- 25 litres

Milk content- 40%

Milk in liters= 25*0.4= 10 litres

Adding x litres of milk to make it 50/50

New total volume is going to be 25+x and milk content will be half of the total:

• 25+x=2*(10+x)
• 25+x= 20+2x
• x=5 litres
