Mixture And Allegation
In what ration must 25% of alcohol be mixed with 50% of alcohol to get a mixture of 40% strent alcohol?

a) 1 : 2
b) 2 : 1
c) 2 : 3
d) 3 : 2



Answer
Solution
Correct Answer Is : 2 : 3
Solution Is : Alcohol + alcohol = alcohol
0.25x + 0.50y = 0.40(x+y)
25x + 50y = 40x + 40y
15x = 10y
x:y = 10:15 = 4:3
Amt of 25% is to Amt of 50% as 2 is to 3.
A vessel contains a mixture of milk and water in the respective ratio of 10 : 3. Twenty-six litre of this mixture was taken out and replaced with 8 litre of water. If the resultant respective ratio of ratio of milk and water in the mixture was 5 : 2, what was the initial quantity of mixture in the vessel ? (in litre)

a) 143
b) 182
c) 169
d) 130



Answer
Solution
Correct Answer Is : 130
Solution Is :
A wholesaler blends two varieties of tea, one costing Rs. 60 per kilogram and another costing Rs. 105 per kilogram. The respective ratio of quantities they were mixed in was 7 : 2. If he sold the mixed variety at Rs. 100 per kilogram, how much was his profit percentage ?

a) 34 2/7
b) 38 2/5
c) 32 2/5
d) 42 6/7



Answer
Solution
Correct Answer Is : 42 6/7
Solution Is : Cost of 9kg of mixture = Rs. (60 × 7 + 105 × 2)
= Rs. (420 + 210) = Rs. 630
S.P of 9 kg of mixture = 9×100 = Rs. 900
Therefore Profit percent = [(900-630)/630]×100
= 2700/63
= 300/7
= 42 6/7 %
In a 90 litres mixture of milk and water, percentage of water is only 30%. The milkman gave 18 litres of this mixture to a customer and then added 18 litres of water to the remaining mixture. What is the percentage of milk in the final mixture ?

a) 64
b) 48
c) 52
d) 56



Answer
Solution
Correct Answer Is : 56
Solution Is : Remaining mixture = 90 - 18 = 72 litres
Milk = (72×70)/100 = 50.4 litres
Water = 72 - 50.4 = 21.6 litres On adding 18 litress of water,
Required percentage of milk = (50.4/90)×100
= 504/9
= 56%
Three tankers contain 403 litres, 434 litres, 465 litres of diesel respectively. Then the maximum capacity of a container that can measure the diesel of the three containers exact number of times is

a) 41 litres
b) 62 litres
c) 31 litres
d) 84 litres



Answer
Solution
Correct Answer Is : 31 litres
Solution Is : Great capacity of measuring vessel = HCF of 403 litres, 434 litres and 465 litres = 31 litres
In a miXture of syrup and water there is 60 per cent syrup. If 5 litres of syrup is added then there is 35 per cent water in the miXture, The initial quantity of miXture was

a) 35 litres
b) 40 litres
c) 32 litres
d) 30 litres



Answer
Solution
Correct Answer Is : 35 litres
Solution Is : Original quantity of miXture = 5X litres syrup = 3X litres; water = 2X litres on adding 5 litres of syrup, percentage of water =2X/5X+5 X 100 2X/5X + 5 X 100 = 35 => 2X/5X + 5 X 20 = 7 => 40X = 35X + 35 5X = 35 X = 7 Original quantity of miXture = 5 X 7 = 35 litres
Two alloys contain tin and iron in the ratio of 1 : 2 and 2 : 3. If the two alloys are mixed in the proportion of 3 : 4 respectively (by weight), the ratio of tin and iron in the newly formed alloy is :

a) 12 : 23
b) 14 : 25
c) 13 : 22
d) 10 : 21



Answer
Solution
Correct Answer Is : 13 : 22
Solution Is : Let 3kg of first alloy and
4kg of second alloy could be mixed together.
Therefore, In 3kg of mixture,
Tin = 1kg
Iron = 2kg.
In 4kg of mixture,
Tin=(2/5)×4 = 8/5 kg=1.6kg
Iron=(3/5)×4=12/5=2.4kg
Therefore,Required ratio
=(1+1.6) : (2+2.4) =2.6 : 4.4
13 : 22
A container has 80 L of milk. From this container 8 L of milk was taken out and replaced by water. The process was further repeated twice. The volue of milk in the container after that is :

a) 85.32 L
b) 58.23 L
c) 85.23 L
d) 58.32 L



Answer
Solution
Correct Answer Is : 58.32 L
Solution Is :
The ratio of the quantities of an acid and water in a mixture is 1 : 3. If 5 litres of acid is further added to the mixture, the new ratio becomes 1 : 2. The quantity of new mixture in litres is

a) 32
b) 40
c) 42
d) 45



Answer
Solution
Correct Answer Is : 45
Solution Is : Let the quantity of acid in original mixture be x litre and that of water be 3x litre.
(x+5)/3x=1/2
=>2x+10=3x
=>x=10
Therefore, quantity of new mixture
=4x+5=45litres.
The ratio of the volumes of water and glycerine in 240cc of a mixture is 1 : 3. The quantity of water (in cc) that should be added to the mixture so that the new ratio of the volume of water and glycerine becomes 2:3 is

a) 55
b) 60
c) 62.5
d) 64



Answer
Solution
Correct Answer Is : 60
Solution Is : In the original mixture,
water = 60 cc
Glycerine = 180 cc
Let x cc of water be mixed.
Therefore (60+x)/180 = 2/3.
==> 180+3x =360
⇒3x= 360 -180 = 180
Hence x=180/3 = 60 cc
