number of girls is 5 more than number
of boys. Find number of boys and girls.​

Answer 1

Answer :-

• Number of boys = 9.
• Number of gîrls = 14.

Step-by-step explanation:

To Find :-

• Number of boys and gîrls in the class.

★ Solution

Given that,

• Total students in class = 28 students.
• Numbers of gîrls more than boys = 5

Assumption

Let us assume number of gîrls and boys as :-

→ Boys = (x)

→ Gîrls = (x + 5)

No. of gîrls + No. of boys = Total students in class,

∴ (x + 5) + (x) = 28

⇒ (x + 5) + (x) = 28

⇒ x + 5 + x = 28

⇒ 2x + 5 = 28

⇒ x + 5 = 28/2

⇒ x + 5 = 14

⇒ x = 14 - 5

⇒ x = 9

The value of x is 9.

Now, According the question,

Total number of gîrls and boys :-

• Gîrls = (x + 5) = (9 + 5) = 14
• Boys = (x) = 9

Hence,

Number of boys and gîrls are 9 and 14 respectively.
