Question

if 40% students in a class are girls and 45 are boys, find total students in class. ​

Answer 1

Answer:

if 40% are Girls Then 60% are boys

Let the total student be x

$\frac{60}{100} \times x = 45 \\ x = \frac{45}{0.6} \\ x = 75$

Total Students are 75

Answer 2

$➝ \: girls \%= 40\%$

$➝ \: boys = 45$

$➝boys\% = 100 - 40 = 60\%$

$\red{let \: total \: studuents \:be\:x}$

$\frac{60}{100} \times x = 45 \\ 0.6 \times x = 45 \\ x = \frac{45}{0.6} \\ x = 75$

Therefore, Total Students are in the class are 75.
