✪ Question ✪

If 45% of the student in a coaching centre are girls and number of boys are 550, find the total number of students and total number of girls.

✪ Given ✪

45% of the student in a coaching centre are girls and number of boys are 550.

✪ To find ✪

The total number of students and total number of girls.

✪ Solution ✪

Percentage of girls = 45 %

So, percentage of boys = (100 - 45) %

= 55 %

Let the total students be x.

According to condition,

55% of x = 550

↝55/100 × x = 550

↝55x/100 = 550

↝55x = 550 × 100

↝55x = 55000

↝x = 55000/55

↝x = 1000

✪ Hence ✪

x = 1000

Total students = x = 1000

Total girls = 45% of 1000 = 450

✪ Therefore ✪

The total number of students is 1000 and that of girls is 450.
