IBPS SO Prelims Exam Model Paper 4

Quantity of milk in the actual solution = [

10

(10+8)

] × 36 = (

5

9

) × 36 = 20 liters
Quantity of water in the actual solution = [

8

(10+8)

] × 36 = (

8

18

) × 36 = 16 liters
Let ‘x’ liters of water be added to this mixture so that the resultant ratio of milk and water is 4 : 6
⇒ [

20

(16+x)

] =

4

6

⇒ (20 × 6) = 4 × (16 + x)
⇒ 30 = 16 + x
⇒ x = 30 - 16 = 14 liters
∴ Quantity of water that should be added = 14 liters
