Question

On the farm the ratio of ducks to geese is 7:4. There are 18 more ducks than geese. What is the total number of ducks and geese

Answer 1

let their are 7x and 4x geese

ATQ

$7x = 4x + 18 \\ 7x - 4x = 18 \\ 3x = 18 \\ x = 6$

the number of duck is 7x = 42

and the number of geese 4x=24

Answer 2

Solutions :-

Given :
The ratio of ducks to geese is 7 : 4

Let the number of ducks be 7x
Number of geese = 4x


According to the question,

=> 7x = 4x + 18
=> 7x - 4x = 18
=> 3x = 18
=> x = 18/3 = 6


Therefore,
Number of Ducks = 7x = 7 × 6 = 42
Number of Geese = 4x = 4 × 6 = 24


Hence,
The total number of ducks and geese are 42 and 24 respectively.
