Answer 2

Answer:

$\underline{\fbox{\rm{500}}}$

Step-by-step explanation:

Given,

• Ratio of boys to girls = 5:3
• Number of girls = 300

To find,

• The number of boys

Let 5x and 3x be the numbers of boys and girls respectively.

Number of girls = 300

⇒3x = 300

⇒x = 300/3

⇒x = 100

Number of boys = 5x

⇒ Number of boys = 5 × 100

⇒ Number of boys = 500

Hence, the number of boys is 500.
