Question

In a class, the number of boys is equal to the number of girls. What was the total number of students if twice the number of boys as girls remain when 12 girls entered out?

Answer 1

Answer:

48

Step-by-step explanation:

no of boys= x

no of girls = y

boys= 2times(girls- 12 out girls)

x = 2 ( y -12 )

but girls = boys

x = y

so x = 2 (x-12)

x=2x-24

24= 2x-x

24= x

girls 24 and boys 24

total class strength 48.
