in a school , 0.8 part of the strength of the school is boys and the number of girls is 150. find the number of boys in the school
Answers
Answer:
600
Step-by-step explanation:
Note: I have solved this question by 2 methods.
1st method
No. of boys = 0.8
Means no. of girls should be 0.2.
Given that,
0.2 girls = 150
Therefore,
0.1 = 150/2
0.1 = 75
Now, We have to find no. of boys.
And we have 0.8
Therefore,
=> 8*75
=> 600
2nd method
Let the total no. of students be x
=> 150=8/10
=> 5X-750=4X
=> X = 750
=> 750-150
=> 600
In this question, we have to just find no. of boys. Girls are given as 150 and they are 0.2.
And boys are 0.8. So, by taking help of 0.8, We can know no. of boys.
