Question

A person spent Rs.$564$ in buying geese and ducks, if each goose cost Rs.$7$ and each duck Rs.$3$ and if the total number of birds bought was $108$, how many of each type did he buy?

Answer 1

Let the number of goose be $x$

Then duck will be $108-x$

Then according to the question ,

$7x+3(108-x)=564$

$4x+324=564$

$4x=240$

$x=60$

Number of goose =$60$

Number of duck=$108-60=48$
