## INTRODUCTION TO MIXTURE AND ALLIGATION:

Hi Aspirants today we are going to discuss on a topic Mixture and Alligation. This topic carries 1 mark in prelims and 2 mark in mains exam.This topic can be implemented in Topics such as Time and Distance ,Ratio and Proportions.

## MIXTURE:

**When two or more components are mixed together then it is known as Mixture**

**Mixture is of two types they are:**

1.Simple Mixture:When two or more different ingredients are mixed together,a simple mixture is formed

2.Compound Mixture:When two or more simple mixtures are mixed together, a compound mixture is formed.

**ALLIGATION:**

** It enables us to find the ratio in which two or more ingredients at the given price must be mixed to produce a mixture of desired price.**

Where M=Mean Value which is between X and Y, X=Cheaper Price, Y=Price higher than the Mean Value

## #.1.TYPE 1:

## MIXTURE CONTAINING TWO OR MORE INGREDIENTS:

**1.A shopkeeper sells rice of 1kg for Rs.75 w two quality of rice whose worth for 1kg is Rs.70 and Rs.80.**

Therefore for 1kg of rice the two quality of rice should be mixed in the ratio **1:1**

## TYPE 2:

## BASED ON PROFIT OR LOSS:

**1.A dishonest milkman professes to sell his milk at cost price but he mixes it with water and thereby gains 25%.The percentage of water in the mixture?**

Let the Cost Price of Pure Milk be Rs.1,

Selling Price of (Milk+ Water) is also Rs.1. which is 25% more than the Costprice

Therefore CostPrice = (100/125)*1=**(4/5)**

The Percentage of water mixed in the mixture =*100=**20%**

**2.The Ratio ,in which tea costing Rs.192 per kg is to be mixed with tea costing Rs.150 per kg so that the mixed tea when sold for Rs.194.40 per Kg,gives a profit of 20%.**

Quality | Cost Price | Selling Price | Selling Price after Profit/Loss |

1^{st} Quality |
150 | 194.40 after 20% profit | |

2^{nd} Quality |
192 |

Finding Selling Price after Giving Profit over Cost Price:

Let the Cost Price be X

Selling Price=X*(120/100) = 194.40

X=(19440/120) **⇒** **X=162**

** **

30:12 **⇒** **5:2**

**The 1 ^{st} and 2^{nd} quality of rice should be mixed in the ratio:5:2**

**Remember:**

**If there is a loss in the transaction indicate it by the ‘-‘ negative sign before the number.**
