Question

In a colony the ratio of male and female is 3: 4. If the no of female is 900 more than male then the no of male is?

Answer 1

the ratio of male and female is 3:4
let the common ratio be x
so male=3x
female =4x
ATQ
female = male +900
4x=3x+900
x=900
So male=3x
=3×900
2700 are males

Answer 2

Answer:

No. of males = 2700

Step-by-step explanation:

Given, ratio of males and females in a colony is 3 : 4

Let the constant be x

Let the number of males be 3x and females be 4x

Given, females are 900 more than male. So, 3x + 900

According to the question,

4x = 3x + 900

=> 4x - 3x = 900

=> x = 900

∴ Number of males => 3x

                                => 3 * 900

                                => 2700
