Answer:
620
Step-by-step explanation:
Given that,
In a school,
No. of boys is 4/9 of total students.
Let the total number of students = x
Therefore, we have,
Number of boys = 4x/9
Also, its given that,
Number of girls = 775
To find the number of boys.
We know that,
Number of boys and number of girls contribute to total number of students.
Therefore, we will get,
=> 4x/9 + 775 = x
Solving further, we get,
=> x - 4x/9 = 775
=> (9x-4x)/9 = 775
=> 5x/9 = 775
=> 5x = 775 × 9
=> x = 9 × 775/5
=> x = 9 × 155
=> x = 1395
Therefore, we will get,
=> 4x/9 = 4 × 1395/9
=> 4x/9 = 4 × 155
=> 4x/9 = 620
Hence, the number of boys is 620.
