A labour gets Rs. 675 for nine days work. How many days should he worked to get Rs. 900?
Given:
A labour gets Rs. 675 for nine days work.
To do:
We have to find the number of days he should work to get Rs. 900.
Solution:
Amount he gets for 9 days of work = Rs. 675
Amount he gets for 1 day of work = $Rs. \frac{675}{9}$
Let the number of he takes to get Rs. 900 be x.
This implies,
Amount he gets in x days = $Rs. x \times \frac{675}{9}$
$900=\frac{675x}{9}$
$x=\frac{900\times9}{675}$
$x=\frac{8100}{675}$
$x=12$
Therefore, he should work for 12 days to get Rs. 900.
