A sum of Rs. 39,00,000 is allotted for providing compensation to the victims of a train accident. The authorities have decided to sanction an amount of Rs. 30,000 to the injured and Rs. 80,000 to the families of the dead passengers. If there are total 65 victims, then find the number of injured passengers.  

Detailed Solution for Test Level 2: Mixtures and Alligations - 1 (August 19) - Question 1

Total amount allotted for compensation to the victims = Rs. 39,00,000
Total victims = 65
Average amount of compensation =
By alligation method,

Therefore,
Ratio of injured to dead passengers = 2 : 3
Number of injured passengers = 
This is our required solution.

A giant watermelon weighs 30 kg, of which 90% is water. After remaining in the sun for one hour, some of the water evaporates such that water makes up 80% of the weight. What is the weight of the watermelon now?  

Detailed Solution for Test Level 2: Mixtures and Alligations - 1 (August 19) - Question 2

Water portion of the watermelon weighs 90% of 30 = 27 kg.
Solid portion of the watermelon weighs 30 - 27 = 3 kg.
When water is 80%, solid portion = 20% 
As 20% = 3 kg; 
Total weight = 3 x 5 = 15 kg

Two liquids A and B are in the ratio 5 : 1 in container X and in the ratio 1 : 3 in container Y. In what ratio should the contents of the two containers be mixed so as to obtain a mixture of A and B in the ratio 1 : 1?  

Detailed Solution for Test Level 2: Mixtures and Alligations - 1 (August 19) - Question 3

Let X units of liquid be taken from container X.
So, liquid A taken = (5/6)X
Liquid B taken = (1/6)X
Let Y units of liquid be taken from container Y.
So, liquid A taken = (Y/4)
Liquid B taken = (3/4)Y
So, as the ratio is 1 : 1, we get
(5/6)X + (Y/4) = (X/6) + (3/4)Y
Or X/Y = 3/4
Hence, the required ratio is 3 : 4.
Thus, option d is correct.

One alloy contains 90% copper and 10% tin. Another alloy contains 93% copper and 4% tin. If they are mixed so that the mixture may contain 9% of tin, then what percent of copper will it contain?
Detailed Solution for Test Level 2: Mixtures and Alligations - 1 (August 19) - Question 5

Apply the rule of alligation,
Quantity of tin

The two alloys should be mixed in the ratio 5 : 1.
Now, amount of copper in the mixture if mixture is 6 units = = 5.43 units
% of copper in the mixture =

A milkman has 48 litres of mixture of milk and water in the ratio 5 : 1, respectively. He withdraws some amount of the mixture from the vessel and replaces it with milk. The ratio of the mixture of milk and water now becomes 7 : 1. What amount of the mixture is withdrawn?
Detailed Solution for Test Level 2: Mixtures and Alligations - 1 (August 19) - Question 6

Capacity = 48 litres
Amount of milk = 5/6 x 48 = 40 litres
Amount of water =1/6 x 48 = 8 litres
Let the amount withdrawn be x.
Thus, 
⇒  x = 12 litres

In what ratio must water be mixed with milk to gain on selling the mixture at cost price?
Detailed Solution for Test Level 2: Mixtures and Alligations - 1 (August 19) - Question 9

Let the C.P. of 1 litre milk be Re. 1. 
S.P. of 1 litre of mixture = Re. 1
Gain = 
C.P. of 1 litre of mixture = (100 x 3/350 x 1) = Rs. 6/7 
So, 6/7 litres of milk is present in 1 litre of mixture. 
Hence, ratio of water to milk = 1/7 : 6/7 = 1 : 6 
Alternate Solution:
To make a profit of 16.67% we need to add 16.67% water.
i.e. we need to add water in milk in the ratio 1 : 6.
