Answer:
It will take both of the brick layers twelve and half days
6 Days
Step-by-step explanation:
First you must find the combined rate of work per day between the two bricklayers.
(100/10)+(100/15) = 16 2/3
For each day the two bricklayers complete 16 2/3 percent of the work. To find out the amount of days it take them to build the wall you divide 16 2/3 from 100
100/16 2/3 = 6
The amount of days it take the two bricklayers to build the wall together is 6.
