A barrel contains a mixture of wine and water in the ratio 3: 1 . How much fraction of the mixture must be drawn off and substituted by water so that the ratio of wine and water in the resultant mixture in the barrel becomes 1 : 1 ?
Answer: (c)
According to the question,
Wine  :  Water  Total  
Initial Ratio  3  :  1  4 
Final Ratio  1  :  1  2 × 2 
1 unit taken out and added
Hence Required part of quantity = $1/3$
Alternative :
Let the quantity of liquid drawn out = x
${3  3/4 x}/{1  1/4 x + x} = 1/1$
12  3x = 4  x + 4x
8 = 6x
x = $4/3$
Hence required part of quantity = ${4/3}/4 = 1/3$
A mixture of 80 litres of wine and water contains 60 percent wine how much water must be added to make it 50 percent wine in the new mixture?
Answer: (d)
According to the question
Given :
Mixture of wine and water = 80 liters
Initial winer concentration = 60 %
Calculations:
Amount of wine in 80 litre of mixture = 60% of 80 = 48 litres
Amount of water in 80 litre of mixture = 80  48 = 32 litres
Also, 50 percent wine in the new mixture means 50 percent water in the new mixture
According to the question,
32 + x = 50/100 × (80 + x)
2 (32 + x) = (80 + x)
64 + 2x = 80 + x
x = 16
∴ x = 16 litres
∴ 16 litres water must be added to make it 50 percent wine in the new mixture.
Water initial mixture pure water
In a mixture of 25 litres, the ratio of acid to water is 4: 1. Another 3 litres of water is added to the mixture. The ratio of acid to water in the new mixture is:
Answer: (d)
According to the question,
Mixture = 25 liters
Ratio of ${Acid}/{Water} = 4/1$ > 5 units
∴ 5 units → 25 liters
1 unit → 5 liters
∴ ${Acid}/{Water} = {4 × 5}/{1 × 5} = 20/5$
Acid  Water  
Initial  20  :  5 
+ 3  
Final Ratio  20  :  8 
[5 : 2]
In a 40 litres mixture of milk and water the ratio of milk to water is 7: 1. In order to make the ratio of milk and water 3: 1, the quantity of water (in litres) that should be added to the mixture will be
Answer: (d)
According to the question,
Milk  :  Water  
Initial Ratio  7 × 3  :  1 × 3 
Final Ratio  7 × 3  :  1 × 7 
Thus, Remember, water is added, not milk, so make milk equal
24 units = 40 liters
1 Unit = $40/24$ liters
4 units = $40/24 × 4$
= $40/6 = 24/3 = 6{2}/3$ liters
How many kg. of salt at 42 Paise per kg must a man mix with 25 kg of salt at 24 Paise per kg, so that he may, on selling the mixture at 40 Paise per kg. gain 25% on the outlay?
Answer: (d)
According to the question,
S.P. of the mixture = 40P per kg.
C.P. of the mixture = 40 × $100/125$ = 32 P per kg
Now using Alligation.
Ratio of Quantity 4 : 5
5 units → 25 kg
1 unit → 5 kg
4 units → 5 × 4 = 20 kg
∴ Salt at 42 P per kg was = 20 kg
