AFCAT Model Paper 5

Given:
Quantity of 1st mixture = 30 liters
The ratio of milk and water in the 1st mixture = 8 : 7
Quantity of 2nd mixture = 20 liters
The ratio of milk and water in the 1st mixture = 7 : 3
Calculation:
30 litres of milk-water mixture contains,
⇒ Milk =

8

15

×30=16 litres
⇒ Water =

7

15

×30=14 litres
20 litres of milk-water mixture contains,
⇒ Milk =

7

10

×20=14 litres
⇒ Water =

3

10

×20=6 litres
Hence, new mixture contains,
⇒ Milk = 16 + 14 = 30 litres
⇒ Water = 14 + 6 = 20 litres
∴ Required ratio = 30 : 20 = 3 : 2
