Mixture and Alligations Questions PDF for Bank
In quantitative aptitude, mixture and alligation are both methods used to solve problems involving the mixing of different substances.
A mixture problem involves mixing two or more substances together and determining certain properties of the resulting mixture, such as its price, weight, or concentration. These problems typically involve ratios and proportions and may require the use of algebraic equations to solve.
Alligation is a method used to solve mixture problems where the ratio of two ingredients is given. It states that, when two or more ingredients are mixed in a certain ratio and sold at a certain price, the ratio of the cost of the ingredients to the selling price is the same as the ratio of the quantity of ingredients. It is a method of finding the average of two or more given ratios.
For example, if you have two types of grain, one costing Rs 4 per kg and the other costing Rs 5 per kg, and you want to create a mixture of the two grains that costs 4.50 Rs per kg, you can use the method of alligation to determine the ratio of the two grains that you need to use to achieve this cost.
In summary, mixture problems can be solved by using ratios and proportions, while alligation is a specific method used to solve mixture problems where the ratio of two ingredients is given, it’s a method of finding the average of two or more given ratios.

Mixture and Alligation Question asked in Previous Year Exam (Sample Question)
Q.1 A jar had 330-liter mixture of Milk and water in the respective ratio of 2 : 1.60 liters of this mixture is taken out and ‘x’ liter each of milk and water is added to the jar (remaining mixture). The respective ratio between milk and water was 8 :5 respectively. What was the total quantity of both milk and water added to the jar?
a) 90 liter
b) 170 liter
c) 160 liter
d) 120 liter
Answer: d
Solution:
Given
Total mixture = 330 liter
Ratio of milk and water = 2 : 1
Calculation
Mixture left in jar after 60 liters taken out = 330 – 60 = 270 liters
Milk = (2/3) × 270 = 180 liter
Water = (1/3) × 270 = 90 liter
Now according to question
(180 + x)/(90 + x) = 8/5
⇒900 + 5x = 720 + 8x
⇒3x = 180
⇒x = 60
∴Quantity that was added = 2 × 60 = 120 liter
Q2. A cistern contains 100 liters of water. 10 liters of water is taken out of it and replaced by the same quantity of soda. This process is repeated one more time. After that 20 liters of the solution is replaced by the same quantity of whiskey. Find the proportion of soda, water, and whiskey in the final mixture?
a) 19 : 71 : 25
b) 38 : 72 : 50
c) 19 : 81 : 25
d) 29 : 71 : 25
Answer: c
Solution:
Given
A cistern contains 100 liters of water.
Calculation
Initially
Water = 100 lit
After 1st replacement
Water : Soda = 90 : 10 = 9 : 1
After 2nd replacement
Water = 90 – (10 × 9/10) = 81 lit
Soda = 10 – (10 × 1/10) + 10 = 19 lit
After 3rd replacement
Water = 81 – (20 × 81/100) = 64.8 lit
Soda = 19 – (20 × 19/100) = 15.2 lit
Whiskey = 20 lit
∴Required ratio = 15.2 : 64.8 : 20
⇒19 : 81 : 25
Q.3) Ratio of Milk and water in Vessel A is 7:4 and same mixture in the ratio of 5:3, 22 liters mixture from vessel A taken out and poured in vessel B new ratio of milk to water is 27:16. If new quantity of mixture in vessel B is equal to initial quantity of mixture in vessel A, then find quantity of Milk after 8 liters of mixture has been taken out from Vessel A?
A) 200/29 liters
B) 546 / 11 liters
C) 120/13 liters
D) 220/19 liters
Answer: b
Let Ratio of Milk and water in Vessel A is 7x and 4y
Let ratio of milk and water in vessel B is 5y and 3y
Now according to question.
(5y + 22 * 7 / 11) / (3y + 22 * 4 / 11) = 27 / 16
(5y + 14 )/ (3y + 8) = 27 / 16
80y + 224 = 81y + 216
Y = 8
New quantity of mixture in vessel B
= > (8 * 5 + 14) + (8 * 3 + 8)
= > 54 + 32
= > 86
Therefore initial quantity of vessel A = 86 liters
Quantity of milk remaining in Vessel A
86 * 7 / 11 – 8 * 7 / 11
= > 546 / 11 litres
Q4. X and Y two alloys are made by mixing aluminum and magnesium metals in the ratio of 8: 5 and 9:16 respectively. If equal amounts of alloys are melted to form a new alloy Z, what will be the ratio of aluminum and magnesium in Z?
a) 317:333
b) 316:319
c) 314:333
d) 313:317
Answer: a
Solution:
The ratio of aluminum and magnesium in Z = [8/13+9/25] : [5/13+16/25]
= 317/325 : 333/325
= 317:333
Q5. How many kilograms of sugar of Rs.5.4 per kg should be mixed with 10 kg of sugar of Rs.4.5 per kg, such that there may be gain of 20% by selling the mixture at Rs.5.94 per kg.
a) 10 kg
b) 12 kg
c) 15 kg
d) 8 kg
Answer: A
Solution:
Let, the amount of rice of Rs.5.4 per kg = x kg
According to the question,
x × 5.4 + 4.5 × 10 = 5.94 × (10 + x) ÷ 120 × 100
=5.4x + 45 = 4.95 × (10 + x)
=5.4x + 45 = 49.5 + 4.95x
=5.4x – 4.95x = 49.5 – 45
=0.45x = 4.5
=x = 10 kg
