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. Reply
Answer:
Given :-
To Find :-
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.
