Answer 2

Given - Ratio and number of girls

Find - Total number of students

Solution - Total strength of the school is 896.

Let the number of boys and girls be 9x and 5x. So, as per the given information -

5x = 320

x = 320/5

x = 64

Therefore, number of boys = 9x

Number of boys = 9*64

Number of boys = 576

Hence total strength of school = 576 + 320

The total strength of school = 896

Thus, the total strength of the school is 896.
