INTRODUCTION TO MIXTURE AND ALLIGATION:

#.1.TYPE 1:

BASED ON ALLOYS:

1.A milk vendor has 2 cans of milk. The  first contains 25% water and he rest milk.The second container 50% water.How much milk should he mix from each of the containers so as to get 12 litres of milk such that the ratio of water to milk is 3:5?

Explanation:

Given that

Milk in 1st Can = 3/4

Milk in 2nd Can =1/2

We want milk in the ratio=5/8

(1/2)*12=6litres  So, quantity of mixture taken from each can=6litre


2.The milk and water in two vessels A and B are in the ratio 4:3 and 2:3  respectively .In what  ratio  the liquids in both vessels be mixed to obtain a new mixture in vessel c consisting half milk and  half water?

Explanation:

Mean Value=(1/2)

Therefore Milk and Water should be mixed in the Ratio of 7:5


#.2 TYPE 2:

FINDING NUMBER  OF PERSONS :

1.In  a zoo there  are Rabbits and Pigeons.If heads are counted ,there are 200 and if legs are counted there are 580.How many pigeons are there?

Explanation:

Total heads Count=200

Total Legs Count=580

Average Leg Count =580/200

= 29/10

Average leg Count for Rabbit =4,

Average leg Count for Pigeons=2

9:11

Thus the number of Pigeons is  * 200=110 pigeons


2.The total number of people in the village is 5000.If the male and female increases by 10% and 15% respectively,the population of the village becomes 5600.What is the number of male in the village?

Explanation:

Total number of people in the village=5000

10% of the village =500   15% of  the village=750

Increased number of people=5600-5000=600

=150:100

=3:2

Male in village=3000   ⇒     (5000*3/5=3000)


#.3. TYPE 3:

PARTIAL WORK:

1.A shopkeeper sells 1000kg of sugar ,part of which he sells at 8% profit and the rest at 18% profit .He gains 14% on the whole. The quantity sold at Rs.18% is?

Explanation:

4:6

=2:3

Therefore  the 1000kg  sugar is sold in the ratio  400:600

Sugar sold at the profit of 18%=600kg
