Step-by-step explanation

Answer 2

Answer:

Given :-

• The ratio of boys to girls in a class is 5 : 3.
• There are 32 students in the class.

To Find :-

• How many of them are boys.

Solution :-

Let, the number of boys be 5x

And, the number of girls will be 3x

According to the question,

⇒ 5x + 3x = 32

⇒ 8x = 32

⇒ x = 32/8

➠ x = 4

Hence, the required numbers of boys and girls are :

➲ The number of boys :

➟ 5x

➟ 5(4)

➟ 5 × 4

➦ 20

And,

➲ The number of girls :

➟ 3x

➟ 3(4)

➟ 3 × 4

➦ 12

∴ The total number of boys and there in the class is 12.

VERIFICATION :-

↦ 5x + 3x = 32

By putting x = 4 we get,

↦ 5(4) + 3(4) = 32

↦ 5 × 4 + 3 × 4 = 32

↦ 20 + 12 = 32

➦ 32 = 32

Hence, Verified.
