1. Question
1 pointsIn what proportion must rice at Rs. 3.10 per kg be mixed with rice at Rs. 3.60 per kg, so that the mixture be worth Rs. 3.25 a kg?
CorrectC.P of 1 Kg. cheaper rice C.P of 1 Kg. dearer rice 310 Paise 360 Paise Mean Price
(325 Paise)35 15 By applying Alligation rule:
(Quality of cheaper Rice)/(Quality of dearer Rice)= 35/15= 7/3
Hence they must be mixed in the ratio 7 : 3.

1 pointsWhat amount of salt at ₹56 per Kg. must a salesman mix with ₹36 Kg. of salt at ₹28 per Kg. so that salesman may, on selling the mixture at ₹48 per Kg., gain 20% on the outlay?
CorrectThe cost price of mixture = 48 × 100/120 P=₹40 per Kg (By the rule of fraction)
56 28 40 12 16 3 4 ∴ Ratio = 3 : 4
Thus for every 4 Kg. of salt at ₹28, 3 Kg. of salt at ₹56 is used.
∴ The required no. of Kg. = 36 × 3/4 = 27 KgIncorrectThe cost price of mixture = 48 × 100/120 P=₹40 per Kg (By the rule of fraction)
56 28 40 12 16 3 4 ∴ Ratio = 3 : 4
Thus for every 4 Kg. of salt at ₹28, 3 Kg. of salt at ₹56 is used.
∴ The required no. of Kg. = 36 × 3/4 = 27 KgUnattemptedThe cost price of mixture = 48 × 100/120 P=₹40 per Kg (By the rule of fraction)

1 pointsA milkman mixes of a certain quantity of milk with 16 liters of water is worth 90 P per liter. If pure milk be worth Rs. 1.08 per liter how much milk is there in the mixture?
CorrectThe mean value is 90 P and the price of water is 0 P.
Milk Water 108 0 90 90 18 By Applying Alligation Rule;
Milk and Water are in the ratio of 5 : 1.
∴ Quantity of milk in the mixture = 5 × 16 = 80 litresIncorrectThe mean value is 90 P and the price of water is 0 P.
Milk Water 108 0 90 90 18 By Applying Alligation Rule;
Milk and Water are in the ratio of 5 : 1.
∴ Quantity of milk in the mixture = 5 × 16 = 80 litresUnattemptedThe mean value is 90 P and the price of water is 0 P.

1 pointsA butler stole wine from a butt of sherry which contained 40% of spirit. He replaced what he had stolen by wine containing only 16% spirit. The butt was then of 24% strength only. How much of the butt did he steal?
CorrectExplanation:
Wine Containing Wine Containing 40% Spirit 16% Spirit Water Containing
(24% Spirit)8 16 ∴ By allegation rule:
(Wine with 40% spirit)/(Wine with 16% spirit)= 8/16= 1/2
i.e., they must be mixed in the ratio (1 : 2). Thus 1/3 of the butt of sherry was left and hence the butler drew out 2/3 of the butt.IncorrectExplanation:
Wine Containing Wine Containing 40% Spirit 16% Spirit Water Containing
(24% Spirit)8 16 ∴ By allegation rule:
(Wine with 40% spirit)/(Wine with 16% spirit)= 8/16= 1/2

1 pointsIn what proportion may three kinds of wheat at Rs. 1.27, Rs. 1.29 and Rs. 1.32 per Kg. be mixed to produce mixture worth Rs. 1.30 per Kg?
CorrectExplanation:
Method 1:
1^{st} Wheat 2^{nd} Wheat 3^{rd} Wheat Mean Price 127 P 129 P 132 P 130 P Here the first two prices are less and the third price is greater than the mean price.
We first find the proportion in which wheat at 127 P and 132 P must be mixed to produce a mixture at 130 P.
(i)1^{st} Wheat 3^{rd} Wheat 127 132 130 2 3 The proportion is 2 : 3.
We next find the proportion in which wheat at 129 P and 132 P must be mixed to produce a mixture at 130 P.2^{nd} Wheat 3^{rd} Wheat 129 132 130 2 1 The proportion is 2 : 1.
∴ The required proportion is = 2 : 2 : 4 = 1 : 1 : 2

6. Question
1 pointsMilk and water are mixed in a vessel A in the proportion 5 : 2, and in vessel B in the proportion 8 : 5. In what proportion should quantities be taken from the two vessels so as to from a mixture in which milk and water will be in the proportion of 9 : 4?
CorrectExplanation:
In vessel A, milk = 5/7 of the weight of mixture
In vessel B, milk = 8/13 of the weight of mixture. Now we want to from a mixture in which milk will be 9/13 of the weight of this mixture.Applying allegation rule:
5/7 8/13 9/13 1/13 2/91 ∴ Required proportion is = 1/13 : 2/91 = 7 : 2
IncorrectExplanation:
In vessel A, milk = 5/7 of the weight of mixture
In vessel B, milk = 8/13 of the weight of mixture. Now we want to from a mixture in which milk will be 9/13 of the weight of this mixture.Applying allegation rule:
5/7 8/13 9/13 1/13 2/91 ∴ Required proportion is = 1/13 : 2/91 = 7 : 2
UnattemptedExplanation:
In vessel A, milk = 5/7 of the weight of mixture

7. Question
1 points300 gm of sugar solution has 40% sugar in it. How much sugar should be added to make it 50% in the solution?
CorrectMethod 1:
The existing solution has 40% sugar. And sugar is to mixed; so the other solution has 100% sugar. So by allegation method:
40% 100% 50% 50% 10% ∴ The ratio mixture should be added in the ratio 5 : 1.
Therefore, required sugar = 300/5 ×1 = 60 gms.Method 2:
Quantity of sugar added = (Solution (Required % value – Present % value))/((100required % value)) = ([300 ×(50 – 40)])/((100 – 50) ) = 60 gms.
IncorrectMethod 1:
The existing solution has 40% sugar. And sugar is to mixed; so the other solution has 100% sugar. So by allegation method:
40% 100% 50% 50% 10% ∴ The ratio mixture should be added in the ratio 5 : 1.
Therefore, required sugar = 300/5 ×1 = 60 gms.Method 2:
Quantity of sugar added = (Solution (Required % value – Present % value))/((100required % value)) = ([300 ×(50 – 40)])/((100 – 50) ) = 60 gms.
UnattemptedMethod 1:
The existing solution has 40% sugar. And sugar is to mixed; so the other solution has 100% sugar. So by allegation method:
40% 100% 50% 50% 10% ∴ The ratio mixture should be added in the ratio 5 : 1.
Therefore, required sugar = 300/5 ×1 = 60 gms.Method 2:
Quantity of sugar added = (Solution (Required % value – Present % value))/((100required % value)) = ([300 ×(50 – 40)])/((100 – 50) ) = 60 gms.

1 pointsA person travels 285 Km in 6 hrs in two stages. In the first part of the journey, he travels by bus at the speed of 40 Km per hr. In the second part of the journey, he travels by train at the speed of 55 km per hr. How much distance did he travel by train?
CorrectExplanation:
By applying the allegation method on the speed.
Speed of Bus Speed of Train 40 55 Average Speed
285/645/6 45/6 ∴ Time spent in bus : Time spent in train = 45/6 : 45/6 = 1 : 1
∴ Distance travelled by Train = 285/2 = 142.5 km.IncorrectExplanation:
By applying the allegation method on the speed.
Speed of Bus Speed of Train 40 55 Average Speed
285/645/6 45/6 ∴ Time spent in bus : Time spent in train = 45/6 : 45/6 = 1 : 1

10. Question
1 pointsA container contained 80 Kg of milk. From this container 8 Kg of milk was taken out and replaced by water. This process was further repeated two times. How much milk is now contained by the container?
CorrectAmount of liquid left after n operation, when the container originally contains x units of liquid form which y units is taken out each time is
=x((x – y)/x)^n units
Thus, in the above case, amount of milk left = =80((80 – 8)/80)^3 Kg. = 58.32 Kg.IncorrectAmount of liquid left after n operation, when the container originally contains x units of liquid form which y units is taken out each time is
=x((x – y)/x)^n units
Thus, in the above case, amount of milk left = =80((80 – 8)/80)^3 Kg. = 58.32 Kg.UnattemptedAmount of liquid left after n operation, when the container originally contains x units of liquid form which y units is taken out each time is
