There are 7178 students in a school and the ratio of boys to girls in the school is 47 : 50, then find the number of boys in school.

Correct option is A

Given:

Total students = 7178

Ratio of boys to girls = 47 : 50

Formula Used:

Number of boys = $$\frac{\text{Total Students} \times \text{Boy’s Ratio Part}}{\text{Total Parts in Ratio}}$$​​

Solution:

Total parts = 47 + 50 = 97

Number of boys = $$\frac{7178 \times 47}{97} = 3478$$​​

Thus, The number of boys in the school is 3478
