IBPS SO Prelims Exam Model Paper 7

Total quantity of mixture = 18 liters and 3 litres of mixture is removed from the container
Now, you are left with only 15 litres of mixture in 3 ∶ 2 ratio.
⇒ Milk in 15 litres mix = 15 ×

3

(2+3)

= 9 litres
⇒ Water in 15 litres mix = 15 ×

2

(2+3)

= 6 litres
We add 3 litres milk to this.
⇒ Milk in new mix is = 9 litres + 3 litres = 12 litres
⇒ Water = 6 litres
∴ Ratio of milk ∶ water = 12 ∶ 6 = 2 ∶ 1
