B. 2:1
C.1:3
D. 3:1​

Answer 1

Required Answer:-

Here we have:-

• A mixture of 35 litres.
• Ratio of milk and water = 4 : 1

To FinD:-

• If 7 liters of water is added, then find the ratio of the given mixture.

Step-by-step Explanation:-

Initially, the mixture was having 35 l of mixture. The ratio of milk and water was 4 : 1. Then,

• Amount of milk = 4/5 × 35 = 28 l
• Amount of water = 1/5 × 35 = 7 l

Now:

7 litres of water is added. Now the total mixture have:

= 35 l + 7 l

= 42 l

Amount of water in the mixture now:

= 7 l + 7 l

= 14 l

Then:

Ratio of milk to water in the mixture now:

= (42 - 14) l : 14 l

= 28 l : 14 l

= 2 : 1

Therefore:-

• The new ratio of milk and water in the mixture after adding some water is 2 : 1 (Ans - $\bf{B}$)
