b. total number of students in the college.​

Answer 1

The ratio of number of boys to girls = 8:5

Number of girls in the class = 160

To find:

Total number of students in the class

Calculation:

Let the number of boys in the class is ‘x’. According to the given data

=> Number of boys/Number of girls = 8/5

=> x / 160 = 8/5

=> x = (8/5)×160

=> x = 256

∴ The number of boys in the class is 256

Total students = number of boys + number of girls

= 256+160

= 416

There are 416 students in the class
