- Mixture and alligation
- Date: 1/1
- Page No: 11

Type - 1
- 12500 students appeared in an exam
- 50% of boys, 70% of girls cleared the examination
- Qualifying % of the total percent of students is needed
- How many girls appeared in the exam?
- Total divided by 2
- 12500/2 = 6250
- 6250 is for both Boys and Girls ie B -> G
Solving
- Boys has 50%, Girls has 70%
- Draw circles and put them together: B 50%, G 70%
- In the middle is the mixture of 60%
- From 70 to 60 is 10%, from 60 to 50 is 10%
- So then it goes to a ratio of 1:1
