Question

the ratio of the number of boys and girls in a school is 4 ratio 3 if there are 360 girls in the school find the number of boys in the school also find the total strength of the school​

Answer 1

Answer:

Step-by-step explanation:

Answer:

No. of boys = 640; No. of girls = 480

Step-by-step explanation:

Let the number of boys = 4x

Let the number of girls = 3x

(We can assume 4x and 3x because 4x and 3x are in the ratio 4:3 and x=0)

ATQ,

4x + 3x = 1120

7x = 1120

x = 160

No. of boys = 4x = 4*160 = 640

No. of girls = 3x = 3*160 = 480

Answer 2

Given :

• The ratio of the number of boys and girls in a school is 4 : 3.
• There are 360 girls in the school.

$\:$

To Find :

• The number of boys.
• The total strength of the school.

$\:$

Solution :

Let

ㅤㅤ★ Number of boys = 4x

ㅤㅤ★ Number of girls = 3x

But, number of girls is 360 (given).

∴ 3x = 360

⇒ x = 360/3

⇒ x = 120

Hence, x = 120.

Now, number of boys :

➠ 4x = 4 × 120 = 480

──

Strength of the school :

$\leadsto\sf{Number \: of \: boys + Number \: of \: girls}$

$\leadsto\sf{480 + 360}$

$\leadsto\sf{840}$

Hence, the total strength of the school is 840.
