Answer 2

$\bold{\underline{\underline{Given\::}}}$

• Total number of students = 1500
• Number of girls = 600

$\bold{\underline{\underline{Find\::}}}$

Ratio of number of boys to number of girls.

$\bold{\underline{\underline{Assume\::}}}$

Let the -

• Number of boys be "M"

$\bold{\underline{\underline{Solution\::}}}$

Total number students = Number of boys + Number of girls

Substitute the known values in above formula

⇒ 1500 = M + 600

⇒ 1500 - 600 = M

⇒ 900 = M

⇒ M = 900

∴ Number of boys = 900

Now,

Ratio of number of boys : Number of girls

⇒ 900 : 600

⇒ 9 : 6

⇒ 3 : 2

∴ 3:2 is the ratio of number of boys to number of girls.
