the number of boys and girls in the class are in the ratio 7: 5 the number of boys is 8 more than the number of girls what is the total strength of class

Answer 1

Answer:

$\huge\red{\boxed{\sf AnSwEr}}$

Let the number of boys be 7x and that of girls be 5x.

According to the given condition, we have

Number of boys = Number of girls +8

⇒7x=5x+8

⇒7x−5x=8 [put 5x to LHS]

⇒2x=8

⇒x= 8/2

→4

Therefore, number of boys =7×4=28 and number of girls =5×4=20

So, total number of children in the class =28+20=48.

Hence, the class strength is $\huge\orange{\boxed{\sf 48}}$

Answer 2

Answer:

24 students

Step-by-step explanation:

let the common factor be x

no . of boys = 7x

no. of girls  = 5x

according to question ,

7x-5x = 8

2x = 8

x = 4

total number of students = 48 students
